Answer:
Explanation:
To calculate the mass of the liquid, we have to use this formula:
 Usually, density will have units of

The mass has units of grams,
#g# . 
The volume will have units of
#mL# or#cm^3#
We are given the density and volume, both of which have good units so all we have to do is rearrange the equation to solve for the mass:
Thus, the liquid has a mass of 31g.
