Question

The volume of a 12.4 g metal pellet is measured by water displacement. It is added to a graduated cylinder filled with water, and the level rises from 10.00 mL to 13.65 mL. What is the density of the metal?

Answer 1

3.39 g.mL⁻¹ or 3.39 g.cm⁻³

Solution:

Data Given:

Mass of Pellet = 12.4 g

Volume of Pellet = 13.65 mL - 10.00 mL = 3.65 mL

Density = ?

Formula Used,

Density = Mass ÷ Volume

Putting values,

Density = 12.4 g ÷ 3.65 mL

Density = 3.39 g.mL⁻¹ or 3.39 g.cm⁻³
