The mass unit associated with density is usually grams. If the volume (in mL or cm3) is multiplied by the density (g/mL or g/cm3) the volume units will cancel out, leaving only the mass units. Keep in mind that the volume and density must use the same volume unit for the cancellation. If a large marshmallow has a volume of 2.00 in3 and density of 0.242 g/cm3, how much would it weigh in grams? 1 in3=16.39 cm3
Homework Answers
Use formula of density=mass÷volume
mass=
density × volume =0.242 × 32.78 = 7.93 grams

For example, the prefix dea is denoted with a d and is associated with a factor of 10- If you were to apply this profix to liter, you would obtain the equality 1 dL -10 L. This could be used to create two conversion factors: 1 dL 10-1 L 10-1 The conversion factor used will depend on whether the final unit should be in...
