Taking into account the definition of density, the density of the rock is 3.6583 g/mL.
Definition of density
Density is defined as the property that matter has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
The expression for the calculation of density is:
density= mass÷ volume
From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.
Density of the rock
In this case, you know that:
- Mass= 88.53 g
- Volume of the rock= Volume after place the rock in the water - Volume of water= 74.2 mL - 50 mL= 24.2 mL
Replacing in the definition of density:
density of rock= 88.53 g÷ 24.2 mL
Solving:
density of rock= 3.6583 g/mL
In summary, the density of the rock is 3.6583 g/mL.
