Question

Find the density of mercury if 205mL has a mass of 2790 g; round your answer tothe nearest0.1 g/mL

Answer 1

D = m / V

D = 2790 g / 205 mL

D = 13.60 g/mL

Answer 2

13.6 g.mL⁻¹

Solution:

The measurement which is employed to compare the mass of a substance to the volume which it has occupied is called as density. The greater the mass or the lesser the volume, the greater is the density on a substance and vice versa.

Data Given;

Density = ?

Mass = 2790 g

Volume = 205 mL

Formula Used;

Density = Mass ÷ Volume

Putting values,

Density = 2790 g ÷ 205 mL

Density = 13.609 g.mL⁻¹
