Verified Answer :

V (volume), M (mass), D (Density)
We get: M = 29.3, and D = 0.7899, And V = ? 
The formula to find the volume is: 
\(V = \frac{M}{D}\)
So we get:
\(V = \frac{29.3}{0.7899}\)
\(V = 37.09\)

So, the volume of acetone when it have a mass of 29.3 grams is about 37.09 milliliters

Hope this Helps! :)
