Question

What is the mole fraction of HCl in a solution that contains 0.99 mole HCl and 3.6 mole H2O

Answer 1

Answer:

  0.216

Explanation:

The mole fraction of HCl is the number of moles of HCl (0.99) divided by the total number of moles in the solution.

  mole fraction = (0.99)/(0.99 +3.6) = 0.2157

The mole fraction of HCl is about 0.216.
