Answer:
The mole fraction is the ratio of moles of solute to moles of solvent. A mole fraction of .78
.78
means that for every mole of HCl, there are .78
.78
moles of water. Molality is the number of moles of solute per mass of solvant. Since HCl has a molar mass of 36.5 g/mol, we would use dimensional analysis to calculate the molality:
