How and why would you use a beaker to measure the density of an object?

A beaker filled with liquid can be used to measure the volume of a non-soluble solid, or of a liquid. If the mass of the solid or liquid sample has been previously determined, the liquid (usually water) displaced from a filled beaker will provide the volume of the sample. Mass divided by volume gives the density.
One of the early uses of the process was to identify counterfeit gold coins. In order to weigh the same as real gold coins, fakes would have to be thicker, and therefore have greater volume.

Which would be the BEST tool to measure 50ml of alcohol?
a beaker
How do you know if your silver ware is real silver?
you could do a density test. If you measure the mass of the object and divide it by the volume (displacement test would be easiest) then you have calculated the density. the density of silver is 10.49 so if you get something close to this then it is silver.
Would you use a beaker or a graduated cylinder to measure isopropyl alcohol?
Graduated Cylinder.
What formula do you use to caculate the density of an object?
Calculate the volume of the substance by measuring the length, width and height. The formula looks like this: Volume = L (length) x W (width) x H (height). Determine if the object or substance is irregularly shaped. If so, you can determine the volume by finding out how much water is displaced when the object is dropped into a beaker of water. Calculate the density once you know the volume and mass of the substance or object. Density is equal to the mass of the substance divided by its volume: D (density) = M (mass) / V (volume).
Does a hydrometer measure density?
Hydrometer is the apparatus measuring relative density of the liquid subject in related to water. The output from measurement after multiplied with water density then would give the density.
What instrument measures the density of an object?
you would use a scale to measure the mass and a beaker to measure the volume. i need another tool
What piece of lab equipment would you use to determine the volume of an irregularly shaped object?
A beaker. Simply fill the beaker with a known quantity of liquid. Drop the object into the beaker, and measure the difference in the fluid levels.
How would measure the density of an object that floats in water?
Push it down to measure the volume.
What units of measure would you use to describe an object's density?
g/cm3
How do you find mass if density isn't given?
You don't need density to find mass. In a lot of question you need to find density with the given mass and volume. But to find density you would use a triple beam balance. To find volume you would either measure the length, width and height or you could fill a beaker up with water lets say 50g and then put the object in the beaker and lets say it raised up to 80g all you have to do is subtract 80g-50g=30g. To find density with volume and mass you divide mass------volume and get density.
Do you have to use a calculator to measure density?
Usually the density of an object is measured by immersing the object into water and then measuring the volume of the water. So no calculator would be required.
What would you use a beaker to measure?
liquid volume
To calculate the density of an object you would?
You need the mass and volume of an object in order to calculate density. density = mass/volume For example, an object has a mass of 25 grams (g) and a volume of 17 cubic centimeters (cm3). According to the density formula, density = 25g/17cm3 = 1.5g/cm3
Why do you have to measure the mass before determining the density?
You have to measure mass before determining density because of the equation D=M/V. If you are somehow unable to find the mass, you can always use an inverse of the equation if you have the measurements of volume and density, which would equal M=DxV.ANS2:You don't need to know the mass if you can measure the object's buoyancy in a liquid whose density is known. For instance: If 10% of an object protrudes from the surface of a liquid with the density of 1g/cm3 (water at 4 deg C) then you know that the density of the object is 10% less than the density of that liquid.
Which would be the BEST tool to measure 50ml of alcohol?
a beaker
What would cause and object to float on fluid?
An object would float on a fluid if the density of the object was less than the density of the fluid.
What instrument measures the volume of an irregular object?
If you submerge the object in a volumetrically-labeled beaker, the volume of water displaced (how much the water rises when the object is submerged), is the volume of the object.Either a graduated cylinder or overflow can is used to measure the volume of an irregular solid by water displacement.
