Question

stone is 90g, water is 50 centimeter cube and water and pebble is 84 centimeter cube, what is the density of stone?​

Answer 1

2.65g/cm³

Step-by-step explanation:

Given parameters:

Mass of stone = 90g

Volume of water = 50cm³

Volume of water and pebble = 84cm³

Unknown:

Density of stone = ?

Solution:

Density is the mass per volume of a substance;

Density =
`(mass)/(volume)`

To find the density of the stone, we know the mass of the stone already. Then let us find the volume of the stone;

Volume of stone = Volume of water and Pebble - Volume of water

= 84cm³ - 50cm³

= 34cm³

So, density of stone =
`(90)/(34)` = 2.65g/cm³
