What volume of a 2% erythromycin solution can be made from 15 gm of erythromycin powder?

The concentration of volume of solution can be expressed in many ways for example: mass percent, volume percent, mass-by-volume percent, etc.

The formula for mass-by-volume percent is:

mass-by-volume percent =

2% erythromycin solution means 2 g of erythromycin in 100 mL.

Consider, for 15 g the volume be X mL.

So,

Hence, the volume is .
