Understand that density is defined as mass per unit volume, expressed mathematically as \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
To determine the density of a liquid, you need to measure two quantities: the mass of the liquid and the volume of the liquid.
A balance (or scale) is used to measure the mass of the liquid accurately.
A graduated cylinder is used to measure the volume of the liquid precisely.
Therefore, the most useful set of equipment to determine the density of a liquid is a graduated cylinder (for volume) and a balance (for mass).
