Question

calculate molefraction of solute if molality is 1 molal

Answer 1

Answer:

here's ur answer mate

Molality is basically number of moles solute present in the 1kg of solvent. Given clearly that 1 molal of aqueous solution hence the solvent here is water. Therefore 1 mole solute present in the 1 kg of water. Molefraction is the ratio of the number of moles of solute and total number of moles in solution.
