Moles = Weight / Molar mass
Moles of NaCl = 5.85 g / (58.5 g/mol) = 0.1 mole
Moles of H₂O = 90 g / (18 g/mol) = 5.0 mole
Mole fraction of NaCl = (Moles of NaCl) / (Total number of moles in solution)
= (Moles of NaCl) / (Moles of NaCl + Moles of H₂O)
= 0.1 mole / (0.1 mole + 5.0 mole)
= 0.1 / 5.1
= 1 / 51
Mole fraction of NaCl in solution is 1 / 51
