Approximately
Explanation:
This requires an assumption that there is 5g solute and 95g solvent in 100g solution. Going from this:
a. Molality is moles of solute over kilograms of solvent; it's a temperature independent measure of solubility.
b. Mole fraction is the ratio of moles of solvent or solute per total moles of components of the solution, thus:
