A dermatologist prescribes drysol as a treatment for excessive underarm sweating. drysol contains 15 g of aluminum chloride hexahydrate in 84 ml of an alcohol base. what is the final strength of drysol?

Respuesta :

Drysol is a mixture of aluminum chloride hexahydrate and an alcohol base.

Mass of aluminum chloride hexahydrate = 15 g

Assuming the density of alcohol base to be 1 g/mL

Mass of alcohol base = [tex] 84 mL * \frac{1 g}{mL} = 84 g [/tex]

Total mass of the mixture = 15 g + 84 g = 99 g

Mass % of the mixture = [tex] \frac{15 g}{99g} * 100 [/tex]

= 15.2 %
