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

1. a caliper and
2. a flask
3. a stopwatch and a beaker
4. a balance and a graduated cylinder
5. a meter stick and a temperature probe

The answer is option 4. a balance and a graduated cylinder.

Explanation:

The graduated cylinder would be used to measure the volume of sea water while a balance will be used to measure the mass. Both values obtained will be used to determine the density of sea water.

b) the inside picture would look at a very high temperature in a very low ph
