Answer:
The answer is
110.2 g
Step-by-step explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
density of rock = 5.8 g/mL
volume = final volume of water - initial volume of water
volume = 12.4 - 10.5 = 1.9 mL
The mass of the rock is
mass = 5.8 × 1.9
We have the final answer as
110.2 g
