Question

A rock weighing 32.0 g is placed in a graduated cylinder displacing the volume from 12.3 mL to 16.8 mL. What is density of the rock in grams /cubic centimeter?

Answer 1

Answer:
Density = 7.11 g.cm⁻³

Solution:

Density is given as,

Density = Mass / Volume --------- (1)

Data Given;
Mass = 32 g

Volume = 16.8 mL - 12.3 mL = 4.5 mL = 4.5 cm³

Putting values in equation 1,

Density = 32 g / 4.5 cm³

Density = 7.11 g.cm⁻³
