To get the mass of acetone, simply multiply the volume of acetone to its density. Since 1 [tex]cm^3[/tex] = 1mL, therefore the volume of acetone is also equal to 17.56 [tex]cm^3[/tex]. In getting the mass,
mass = volume*density
[tex]mass = 17.56 cm^3 ( \frac{0.7857g}{cm^3} ) \\ mass=13.797g[/tex]
The mass of the acetone is 13.797g.
