To find the mole fraction of solute in a one molal aqueous solution, we can follow these steps: 1. Understand the Definition of Molality: - Molality (m) is defined as the number of moles of solute per kilogram
Percent by mass of solute (molar mass = 25 g/mol) in its aqueous solution is 30. The mole fraction and molality of the solute in solution are
