Question

Arwan finds a piece of quartz while hiking in the mountains. When he returns to school, he takes it to his science teacher. She helps him determine the mass to be 788.9 g. She also tells Arwan that the density of quartz is 2.6 . What is the volume of Arwan’s piece of quartz?

Answer 1

Volume of quartz = mass of quartz/density of quartz = 788.9/2.6 = 303.42mL.

Answer 2

Answer: The volume of Arwan’s piece of quartz is
`303.42 cm^3`

Step-by-step explanation:

Mass of the Quartz piece brought by Arwan : 788.9 g

Density of the quartz =
`2.6 g/cm^3`

Density of the substance is defined as mass present in per unit volume of the substance. It is measured in gram per centimeter cube.

`density=(mass)/(volume)`

`density=2.6g/cm^3=(mass)/(volume)=(788.9 g)/(volume)`

`volume=(788.9 g)/(2.6 g/cm^3)=303.42 cm^3`

Hence,the volume of Arwan’s piece of quartz is
`303.42 cm^3`
