What is the volume in milliliters of 6.58g of acetone

M=6.58 g

ρ=0.7899 g/ml

v=m/ρ

v=6.58g / (0.7899g/ml) = 8.33 ml

We are missing information here. to convert mass (grams) to mL (volume) we need density

since it was not given, i look it up online. density = 0.791 g/mol

density formula---> density = mass / volume

we can rewrite this formula to solve for volume

volume = mass / density

volume = 6.58 grams / 0.791 = 8.32 mL
