Question

An empty density bottle of 50 ml capacity weighs 26.9 g. When filled with liquid, it weighs 53.4 g. Find the density of the liquid and express it in the SI unit.

Answer 1

Answer:

1300kg/m

Explanation:

The mass of the bottle is given as 30 g.

The mass of the liquid is given as 53.4 g - 30 g = 23.4 g.

The mass of water is given as 48 g - 30 g = 18 g = 0.018 kg.

The volume is calculated.

We know, Density = Mass / Volume.

As the mass of water is determined and the density of water is given, the volume of water is given as follows.

Volume = Mass / Density = 0.018 / 1000 = 18×10
