Chemistry, d=m/v

Question

You decide you want to carry a boulder home from the beach. It is 30.0 centimeters on each side. It is made of granite, which has a typical density of 2.8 g/cm^3. How much will this boulder weigh?

Answer 1

V = s^3

= (30.0)^3

= 27,000 cm^3

d = m / V

m = d x V = 2.8 g/cm^3 x 27,000 cm^3 = 75,600 g
