Question

What is the density of an block of salt having a mass of 8.0 g and a volume of 25 cm3?

Answer 1

D = m/v

D = 8g / 25 cm^3 x 1000,000 cm^3/1000g

D = 320 kg/ m^3 or 0.32g/cm^3

(I actually calculated, not copied)

Answer 2

Answer: The density of the block will be
`0.32g/cm^3`

Explanation:

Density is defined as the mass contained per unit volume.

`Density=(mass)/(Volume)`

Given : Mass of block = 8.0 grams

Volume of block=
`25cm^3`

Putting in the values we get:

`Density=(8.0g)/(25cm^3)=0.32g/cm^3`

Thus density of the block will be
`0.32g/cm^3`
