Question

A rock that weighs 12.2 g is added to a graduated cylinder with 30.0 mL of water in it. The meniscus rises to 54.4 mL. What is the density of the rock?

Answer 1

Answer:

              0.50 g/mL

Explanation:

Formula of Density,

                          D = mass / volume

Mass = 12.2 g

Volume = 54.4 mL - 30.0 mL = 24.4 mL

Putting values,

                          D = 12.2 g / 24.4 mL

                          D = 0.50 g/mL
