Acetone, a common solvent has a density 0.79g/cm^3 at 20C. What is the volume of 85.1g of acetone at 20C? What is the mass of 125ml of acetone at 20C? Show your calculations.

Answer 1

mass = volume x density or
volume = mass/density
mass = 85.1g
density = 0.79 g/cc
solve for volume

b.
mass = volume x density
density from above
volume = 125 mL = 125 cc
solve for mass

Answer 2

volume is 107.72ml, mass is 85.098 g
