Answer to Question #236190 in General Chemistry for Roy Gerald

Question

An acid, HEl, is formed from a hypothetical element, El, and a subsequent aqueous solution is created with the acid and water. The solution is measured to be 22.49% HEl by weight. Calculate the mol % of the acid in the solution.

Atomic Mass:

H: 1.00784 g/mol

O: 15.999 g/mol

El: 142.76243 g/mol

Answer 1

Now, mole fraction of water =2.741.4​=0.51

mole fraction of Ethanol =2.740.54​=0.197

mole fraction of acetic acid =2.740.8​=0.291
