The most accurate way to determine an object’s volume, especially in the case of an irregularly shaped object, is to immerse it in water and measure the amount of water it displaces. A
large enough to hold both the object and enough water to fully immerse it is the best tool for this job.Key Takeaways: How to Calculate Density
The density equation is density equals mass per unit volume or D = M / V. The key to solving for density is to report the proper mass and volume units.hydrometer, device for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).

Why is the water displacement method more accurate than measuring?
For the smaller objects, students may be able to simply submerge the object into a partially filled graduated cylinder. The change in water level equals the volume of the submerged object. This method is more accurate than measuring water that has spilled out an overflowing beaker.
Which is the most accurate method of volume measurement?
Volumetric flasks, burets and pipets are the most accurate with tolerances of less than 0.2%.
What two methods of determining density will be used in this experiment?
- Direct Measurement of Mass and Volume. When measuring liquids and regularly shaped solids, mass and volume can be discovered by direct measurement and these two measurements can then be used to determine density. …
- Indirect Volume Measurement. …
- Estimated Density using Archimedes Principle.
What other methods are used to determine the density of liquid?
To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container.
Why the density bottle method is more accurate?
In finding the density of liquid, why is the method of using a density bottle more accurate than the one of using a measuring cylinder? Answer Text: This is because a density bottle is built to have the exact volume of water hence no errors in reading the meniscus compared to a measuring cylinder.

Which method for finding density was the most accurate, justify …
Explanation: This method requires a water-filled container with graduated volume markings. A kitchen measuring cup would suffice, …
The Best Way to Check Density – Sciencing
After the mass and volume of the solid or liquid have been measured, divide the mass by the volume to calculate the density.
Lab 1 – Density Determinations and Various Methods to …
In this experiment, you will measure masses and volumes to determine density. Four different metal cylinders are investigated.
Measuring Density with Laboratory Balance – Mettler Toledo
The most widely used method is the buoyancy technique which utilizes Archimedes’ principle: a body immersed in fluid indicates an apparent loss in weight equal …
How do you determine density experimentally?
To find the total Volume displaced, subtract Initial Volume and Volume of Object. To calculate Density divide the Mass in grams by the Volume displaced in milliliters. Finally record whether the object floats or sinks.
What are the different techniques for density measurement?
- Hydrostatic Pressure. This type of density measurement relies on a constant height of liquid and measures the pressure differences. …
- Radiation. …
- Vibration. …
- Differential Pressure. …

How accurate is water displacement?
Device to measure volume of water is usually a graduated cylinder, and are accurate to about 0.2% of the volume you are measuring.
What is the most accurate measuring device in chemistry?
The volumetric flask is the most accurate, but it only measures 1 volume—in this case, 100mL. If you need to measure other volumes besides those on volumetric flasks, then the graduated cylinder is the best tool. The beaker is pretty accurate, and you can easily stir and heat chemicals in it.
Why is the volumetric pipette the most accurate?
The main advantage of a volumetric pipette is its accuracy. It is especially precise when it is delivering solutions, as another advantage of the standard build is its narrow neck. This allows for the meniscus to be read more accurately, and therefore deliver more precise results than graduated pipettes.
What is the least accurate way to measure volume?
- Beaker. the least accurate instrument for measuring volume (5% accuracy)
- Erlenmeyer Flask. used to measure approximate volumes, mixing, and sample storage (5% accuracy)
- Graduated cylinder. used to measure the volume of a liquid (1% accuracy)
- Volumetric Flask. …
- Buret. …
- Volumetric Pipette.
Which determination of density do you think has the highest error?
It is an intrinsic property so it can be used to identify a substance. Which determination of density has the highest error? The spring scale.
What do you mean by hydrometer?
Definition of hydrometer
: an instrument for determining the specific gravity of a liquid (such as battery acid or an alcohol solution) and hence its strength. Other Words from hydrometer Example Sentences Learn More About hydrometer.
How do you find the density of water experiment?
- Find the mass of an empty graduated cylinder. …
- Pour 100 mL of water into the graduated cylinder. …
- Weigh the graduated cylinder with the water in it. …
- Find the mass of only the water by subtracting the mass of the empty graduated cylinder. …
- Use the mass and volume of the water to calculate density.
How do you find density in chemistry?
The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
How does a Eureka can work?
A eureka can is a container large enough to hold the object with a spout positioned near the top. The can is filled to the top with water and the object placed in it. The volume of the object is equal to the volume of the water that is forced through the spout.

How density bottle is used to find the density of a liquid?
When the bottle is filled with liquid and stopper is inserted, the excess liquid rises through the hole and drains out. Thus the bottle will contain the same volume of liquid each time when it is filled. It is used to determine the density of a liquid.
What are some advantages of finding density by measurements?
- • Not heavily influenced by plot size since. expressed on area basis.
- • Sensitive to changes in recruitment and. mortality.
- • Not sensitive to changes in phenology. • Easy to measure.
