Question

15. The mass of an ice block is 125 g. If density of
ice is 0.92 gcm-3, find the volume of ice block.
1125 87 cm3 division
​

Answer 1

Given that, Mass (m) of an ice block is 125 g and density (d) of ice is 0.92 g/cm³.

We have to find the volume of the ice block.

Density is defined as the ratio of mass per unit volume.

i.e.

Density = mass/volume

Substitute the known values

0.92= 125/volume

volume= 125/0.92

volume=135.87 cm³

• If an object is greater than 1, then it will sink in water. Otherwise, it will float.

• Unit of mass is g (gram) and for volume is cm³. Therefore, the unit of density is g/cm³.
