If you want to CALCULATE the density of an unknown substance, you need to divide its mass by its volume, so you need to measure both first. If it is a homogeneous (uniform) substance, and you can take away a piece, you can take any sample. Any piece of the substance will have the same density.

What procedures would you follow if you wanted to calculate the density of an unknown substance?

To calculate the density of an unknown substance, first measure its mass using a balance. Then, determine its volume by either measuring its dimensions and calculating the volume or using displacement method in a liquid. Finally, divide the mass by the volume to calculate the density of the unknown substance.


When you divide the mass of a substance by its volume you get its what?

You get its density. Density is a measure of how much mass is contained within a specific volume of a substance.


What is the equation used for calculating density?

density = mass/volume


What is density lab?

Density lab is an experiment conducted in a laboratory setting to determine the density of a substance. It involves measuring the mass and volume of a sample and then calculating the density by dividing the mass by the volume. Density is a property of matter that describes how tightly packed the particles are within a substance.


How do you calculate the density of a substance?

The density of a substance is calculated by dividing its mass by its volume. The formula for density is: Density = Mass / Volume. This calculation gives you a measure of how tightly packed the molecules are in a given sample of the substance.


What mistake did Andrew make in calculating density?

Andrew made a mistake in calculating density by not properly measuring the volume of the object. Density is calculated by dividing the mass of an object by its volume, and if the volume is incorrect, it will lead to an inaccurate density value.


How can you change density of a substance?

You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.


If you know the density and volume of a substance how could you find its mass?

You can find the mass of a substance by using the formula mass = density x volume. Multiply the density of the substance by its volume to calculate the mass.


How much mass there is in a volume of a substance?

If the density of the substance is known, then you can calculate it. Density = Mass/Volume, so Mass = Density x Volume


Is the density of a substance obtained by dividing its volume with its weight?

The density is measured by dividing the mass of the substance with it's volume. Density = Mass/Volume.


What is the formula for calculating density if the mass and volume of an object are known?

The object's density = (its mass) divided by (its volume)


How could density be used to determine the mass of a particular volume of a substance?

To determine the mass of a particular volume of a substance using density, you would multiply the density of the substance by the volume of the sample. The resulting value would give you the mass of the substance based on the known density and volume relationship (mass = density x volume).
