The mass unit associated with density is usually grams. If the volume (in mL or cm^ 3 ) is multiplied by the density (g/mL or g/cm^ 3 ) volume units will cancel outleaving only mass units. Keep in mind that the volume and density must use the same volume unit for cancellation. If a large marshmallow has a volume of 3.00i * n ^ 3 and density of 0.242 g/cm^ 3 , how much would it weigh in grams? 1i * n ^ 3 = 16.39 cm ^ 3
