What is the mass, in grams, of 28.66 ml of acetone?

Answer is: mass of acetone is 22.51 grams.:

V (acetone - C₃H₆O) = 28.66 mL; volume.

d (acetone) = 0.7857 g/mL; density.

m (acetone) = V (acetone) · d (acetone).

m (acetone) = 28.66 mL · 0.7857 g/mL.

m (acetone) = 22.51 g; mass.

Acetone or propanone is the colorless, volatile, flammable organic compound (ketone).

When mass = density * volume

and we here have the density of acetone = 0.7857 g / Cm^3

and the volume = 28.66 mL

so by substitution:

∴ the mass of the acetone = 0.7857g * 28.66

= 22.5 g
