What is the molality of a solution made by dissolving 14.7 g of C₆H₁₂O₆ into 150.0 mL of water? Assume the density of water is 1.00 g/mL.

Question

Quizplus · Accepted Answer

Molality (m) is calculated as moles of solute per kilogram of solvent. The molar mass of C6H12O6 is 180.18 g/mol. Moles of C6H12O6 = 14.7 g / 180.18 g/mol = 0.0816 mol. Mass of water = 150.0 g = 0.150 kg. Molality = 0.0816 mol / 0.150 kg = 0.544 m.
