<u>Answer:</u> The volume of acetone having 85.1 g of mass is
. The mass of acetone having volume of 125 mL is 98.75 g.
<u>Explanation:</u>
To calculate mass of a substance, we use the equation:
......(1)
- <u>For the calculation of volume:</u>
Density of acetone = 
Mass of acetone = 85.1 g
Putting values in equation 1, we get:

The volume of acetone for the mass of 85.1 g is 
- <u>For the calculation of mass:</u>
We are given:
Density of acetone = 
Volume of acetone =
(Conversion factor:
)
Putting values in equation 1, we get:

Hence, the mass of acetone for the volume of 125 mL is 98.75 g
