Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?

In order to measure density, a measurement of volume and mass is required. To measure the density of seawater, the volume could be measured using a glass graduated beaker and the mass could be measured using a set of digital scales. Be sure to take into account the mass of the beaker.

Unfortunately, we are not given with the choices in which we could have chosen our answers from. However, in order to determine the mass of an object, we use the balance or the weighing scale. Also, for the volume of the water by graduated cylinder. Then, we divide the mass by the volume.
