What is the volume, in milliliters, of 6.56g of acetone?

The density of the compound of acetone is equal to 0.791 g/mL. The volume is calculated by dividing the mass given by the density. Mathematically, that is,

v = m / ρ

Substituting the known values,

v = 6.56 g / (0.791 g/mL) = 8.29 mL

Thus, the volume of the acetone is approximately equal to 8.29 mL.
