Variables Used

Mole Fraction of Solute - Mole Fraction of Solute is the ration of the number of moles of the solute to the total number of moles of the solute and solvent.
Molality - (Measured in Mole per Kilogram) - Molality is defined as the total number of moles of solute per kilograms of solvent present in the solution.
Molar Mass of Solvent - (Measured in Kilogram) - The Molar Mass of Solvent is the molar mass of the medium in which the solute is dissolved.

STEP 1: Convert Input(s) to Base Unit

Molality: 0.034 Mole per Kilogram --> 0.034 Mole per Kilogram No Conversion Required
Molar Mass of Solvent: 25 Gram --> 0.025 Kilogram (Check conversion here)
