Answer:

The mass of the rubbing alcohol is 14.77 g

Explanation:

The formula to be used here is that of density which is shown below

Density = Mass ÷ volume

The density of the rubbing alcohol (also known as isopropyl alcohol) is given in the question as 0.79 g/ml while the volume of same is given as 18.7ml. The mass of this rubbing alcohol is the unknown (which we can derive from the formula given earlier).

Hence,

Mass = Density × volume

Mass = 0.79 × 18.7

Mass = 14.77 g
