Question

Drysol contains 15g aluminum chloride hexahydrate in 84ml of alcohol base what’s the strength of drysol?

Answer 1

Answer : The strength of drysol is 178.55 g/L.

Solution : Given,

Mass of aluminium chloride hexahydrate = 15 g

Volume of alcohol = 84 ml

Molar mass of Drysol = 241.422 g/mole

First we have to calculate the concentration of drysol.

`C=(w* 1000)/(M* V(inL))`

where,

C = concentration of drysol

w = Mass of drysol

M = molar mass of drysol

V = Volume of drysol

Now put all the given values in above formula,we get

`C=(15g* 1000)/(241.422g/mole* 84L)=0.7396mole/L`

Now we have to calculate the strength of drysol.

Strength of drysol = Concentration of drysol × Molar mass of drysol

Strength of drysol = 0.7396 mole/L × 241.422 g/mole = 178.55 g/L

Therefore, the strength of drysol is 178.55 g/L.
