A student pours liquid into a measuring cylinder.
The student records the volume of the liquid from the scale on the measuring cylinder. He then puts the measuring cylinder containing the liquid on a balance and records the mass.
What else needs to be measured before the density of the liquid can be calculated?

A student wishes to measure accurately the volume of approximately 40 cm^3 of water. She has two measuring cylinders, a larger one that can hold 100 cm^3, and a smaller one that can hold 50c m^3. The water forms a meniscus where it touches the glass.
Which cylinder should the student use and which water level should she use to ensure an accurate result?
