According to Charles Law :

Hello!

To find the density of copper, we would need to use the density formula.

The formula for density is: d = m/V. In this formula, d is the density, m is the mass, and V is the volume.

We are given the mass, which is 140.125 grams. But, we are only given a side of length of a cube, which is 2.50 centimeters.

The volume of a cube is found by multiplying the height, width, and length together. A cube has 6 squares, with all the sides being equal to one other, so, the height, width and length are 2.50 centimeters.

V = l × w × h

V = 2.50 × 2.50 × 2.50

V = 15.625 cm³

With those values, we can substitute them into the formula, and solve for the density.

d = 140.125g/15.625cm³

d = 8.968 g/cm³

Therefore, the density of copper is 8.968 g/cm³.
