1. you have 2 m3 of a mineral ore sample. it has a mass of 1 _ 104 kg. calculate the density of the ore sample and express your results in g/cm3 with appropriate scientific notation

The solution to your problem is as follows:

2 m3 is 2e6 cm3 

1e4 kg is 1e7 g 

so 

d = m/V = 1e7/2e6 = 5 g/cm3

Therefore, the density of the ore sample is 5 g/cm3.
