A Drysol prescription contains 15g of aluminium chloride in 84mL of an alcohol base, what is the final strength of Drysol?

Answer 1

Answer:

Explanation:

Mass of aluminum chloride hexahydrate

15g

Density of alcohol base 1g/ml

Mass of alcohol base

84ml*1g/ml =84g

Total mass of mixture

15g + 84g =99g

Mass % of mixture

15g/99g * 100 = 15.2%

Strength of Drysol is 15.2%
