A solution of LiCl in water has X_LiCl = 0.0500.What is the molality? A)2)60 m LiCl B)2)77 m LiCl C)2)92 m LiCl D)5)26 m LiCl

Question

Quizplus · Accepted Answer

Molality (m) is calculated using the formula: m = (moles of solute) / (kg of solvent). Given X_LiCl = 0.0500, the mole fraction of water is 0.9500. Assuming 1 mole of solution, moles of LiCl = 0.0500 and moles of water = 0.9500. The mass of water is 0.9500 moles * 18.015 g/mol = 17.11425 g = 0.01711425 kg. Molality = 0.0500 moles / 0.01711425 kg = 2.92 m.
