Answer:

5 g/cm³

Explanation:

Density is the amount of matter contained by an object in a certain space. Density is the ratio of mass to volume. Density is given by the formula:

Density = mass / volume

We can see from the question, that initially the measuring cylinder contained a liquid with a volume of 100 cm³, but after the rock sample was immersed in the liquid, the volume rised up to 140 cm³. Hence:

The volume of rock sample = 140 cm³ - 100 cm³ = 40 cm³

Also, initially, the balance was at 0 g, but after placing the rock sample, it was 200 g. Hence:

mass of rock sample = 200 g

Therefore, Density of rock sample = mass of rock sample / volume of rock  sample = 200 g / 40 cm³ = 5 g/cm³
