The correct answer is a balance and a graduated cylinder.

The density or more accurately, the volumetric mass density, of a substance is its mass per unit volume. A balance can be utilized to determine the mass of the sample, and the volume of the sample can be calculated by positioning the sample in the graduated cylinder occupied with water or any other form of liquid.

The correct answer is a balance and a graduated cylinder.

The density or more accurately, the volumetric mass density, of a substance is its mass per unit volume.
