Question

calculate the mole fraction of hcl in a solution of hcl in h2o containing 36%hcl by weight​

Answer 1

Explanation:

Explanation:

You know that your solution is

20

%

hydrochloric acid by mass, which means that every

100 g

of this solution contain

20 g

of hydrochloric acid, the solute.

To make the calculations easier, pick a sample of this solution that has a mass of exactly

100 g

. Since you already know that this sample contains

20 g

of hydrochloric acid, you can say that the mass of water, the solvent, will be

mass of solvent

Nest, use the molar mass of hydrochloric acid and the molar mass of water to convert the masses to mole.

Answer 2

Explanation:

h2o=36/6=6

therefore weight is 6
