Question

A sample of an unknown liquid has a volume of 12.0 mL and a mass of 6 g. What is its density?

Answer 1

Density = Mass divided by Volume, or d = m/v.
So, replace the m and v with the amounts given:
d = 6/12.
Therefore, d = 0.5. 

Answer 2

The answer is 0.5g/ml

The volume of the unknown liquid is 12.0 ml

The mass of the liquid is 6g

The density can be calculated as follows

= 6/12

= 0.5  g/ml

Hence the density of the unknown liquid is 0.5g/ml
