Hi,
Thank you for posting your question on embibe. Hope your prepration is going well.
Here is the answer to your question
Molality, M = moles of solute/kg of solvent
Mole fraction, xA = nA/nA+nB, xB= nB/nA+nB
p1 = x1po1
∴ x1 = p1/po1

Answer:
Molality m = moles of solute / kg solute
Explanation:
Mole fraction, xA = nA/nA+nB, xB= nB/nA+nB
p1 = x1po1
∴ x1 = p1/po1
