Question

A 22.4g sample of a substance was added to a graduated cylinder. It caused an 18.3 mL change in the volume of the water in the cylinder. What is the density of the substance?

Answer 1

Density = 1.22 g.mL⁻¹

Solution:

Data Given:

Mass = 22.4 g

Volume = 18.3 mL

Density = ??

Formula used;

Density = Mass ÷ Volume

Putting values,

Density = 22.4 g ÷ 18.3 mL

Density = 1.22 g.mL⁻¹
