Question

The mineral sample in this graduated cylinder has a mass of

30.4 g. When placed in the cylinder, the water level changed from 60 mL to 64 mL. Calculate
the density

Answer 1

Density is defined as mass per unit volume. To calculate the density of the mineral sample, you can divide its mass by its volume. The volume of the mineral sample can be calculated from the change in water level in the graduated cylinder when it was placed in it.

The change in water level is 64 mL - 60 mL = 4 mL. Since 1 mL is equivalent to 1 cm3, this means that the volume of the mineral sample is 4 cm3.

Now that we have both mass and volume of the mineral sample, we can calculate its density:

Density = Mass / Volume

= 30.4 g / 4 cm3

= 7.6 g/cm3

The density of the mineral sample is 7.6 grams per cubic centimeter (g/cm3).
