Density d=m/v
1. a rock has a mass of 43g and a volume of 34 mls at 4390 feet. what is its
density?

1.265 g/mL

We are given;

We are required to calculate the density of the rock.

Density is the mass of an object per unit volume.

It is calculated by;

Density = Mass / volume

Therefore;

Density = 43 g ÷ 34 mL

             = 1.265 g/mL

Thus, the density of the rock is 1.265 g/mL
