Question

If you have a density of 3 g/mL and a mass of 15 g, what is the volume?

Answer 1

d= 3g/ml
m= 15g
v=
d= m/v
v=m.d
15.3
=45g/ml

Answer 2

In order to solve the question we must know the relation in between density, mass and volume.

The ratio of mass and volume gives the density of an object.

i.e. Density = mass per unit volume = mass/volume.

or, Volume = mass / density.

or, Volume = 15 / 3 = 5 ml. [Ans]

Therefore, the volume is 5 ml.
