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.

$Density=\frac{mass}{Volume}$

Given : Mass of block = 8.0 grams

Volume of block= $25cm^3$

Putting in the values we get:

$Density=\frac{8.0g}{25cm^3}=0.32g/cm^3$

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