You need 1400 kg of rock. This rock has a density of 3.3 grams/cm^3. What is the volume of rock that you need to acquire from the quarry, in cubic meters?

Question

This is a unit conversion question for chemistry. 

Answer 1

Density = Mass/Volume

 

3.3 g/cm^3 = 1400 kg/ V

 

3.3 g/cm^3 = 1400000 g/V <--- converts kg to grams

 

V cm^3= 1400000 g/ 3.3 g

 

424242.42  cm^3

 

1 cubic meter = 100^3 cm^3

 

424242.42/1000000

 

0.42 cubic meters
