How can I calculate the amount of matter in a given volume?

Answer 1

Use the density equation: density = mass/volume.

The density equation, density = mass/volume, can be used to determine the amount of matter in a given volume of a sample. A substance's mass is its amount of matter.

In this example, I'll use the element copper, and you can look up the element's density using a chart. To use the density equation to find mass, you need to know the volume of your sample and its density.

Work with the equation to get mass = (density)(volume) in order to find mass from density and volume.

Example: What is the mass of a sample of copper that has a volume of #8.00cm^3#?

Known or Given: Cu volume = #8.00cm^3# density of copper at #20^"o"#C = #8.96#g/#cm^"3"# https://tutor.hix.ai

Density is equal to mass times volume.

Solution: mass = (density)(volume) = (#8.96#g/#cm^"3"#)(#8.00cm^3#) = 1.12g Cu

To calculate the amount of matter in a given volume, use the formula: mass = density × volume.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
