A 15 percent by mass glucose solution is given. What is its approximate molality?

Answer and explanation

Correct answer: 0.98 mol kg−1

Assume 100 g solution. It contains 15 g glucose and 85 g water. Moles of glucose = 15/180 = 0.0833 mol, and solvent mass = 0.085 kg. Hence molality = 0.0833/0.085 ≈ 0.980 mol kg−1. The denominator is the mass of water only, which is why using 100 g would produce a wrong result.
