D)4)56

Question

Quizplus · Accepted Answer

The mole fraction of LiCl is 0.0853. This can be calculated using the following formula:Mole fraction of LiCl = (moles of LiCl) / (total moles of solution)The moles of LiCl can be calculated by dividing the mass of LiCl by its molar mass. The total moles of solution can be calculated by dividing the mass of the solution by the molar mass of water.Once the moles of LiCl and the total moles of solution are known, the mole fraction of LiCl can be calculated by dividing the moles of LiCl by the total moles of solution.
