Question

A straightforward method of finding the density of an object is to measure its mass and then measure its volume by submerging it in a graduated cylinder. What is the density (in g/cm3) of a 260 g rock that displaces 83.0 cm3 of water?

Answer 1

Density of rock will be equal to
`3.13g/cm^3`

Step-by-step explanation:

It is given that mass of the rock
`m=260gram`

Volume displaced bu rock
`V=83cm^3`

We have to find the density of rock

Density is equal to ratio of mass and volume

Therefore density of rock
`\rho =(m)/(V)`

`\rho =(260)/(83)=3.13g/cm^3`

So density of rock will be equal to
`3.13g/cm^3`
