What is the mass in grams of 13.06 mL of acetone

Acetone (fingernail-polish remover) has a density of 0.7857 g/cm3

To know the mass of the acetone we must multiply the volume of the acetone with its density. but since the volume is in ml units and the density is in g/cm3. we must convert it firstsince 1 ml = 1 cm3

so mass acetone = 13.06 mL (0.7857 g/ml) mass acetone = 10.848 g
