Question

What is the density (g/mL) of an object that has a mass of 0.03 kg and occupies a volume of 25 mL?

Answer 1

First convert the kg to g ----- 0.03kg = 30g
Then divide the mass by the volume ----- 30g ÷ 25mL = 1.2
The density is 1.2g/mL

Answer 2

Answer : The density of an object is 1.2 g/mL

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used :

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

Given :

Mass of object = 0.03 kg = 30 g

conversion used : (1 kg = 1000 g)

Volume occupied by object = 25 mL

Now put all the given values in the above formula, we get :

$Density=\frac{30g}{25mL}=1.2g/mL$

Therefore, the density of an object is 1.2 g/mL
