What is the molality of ethanol in a solution made by dissolving 14.6 g of ethanol,C₂H₅OH,in 53.6 g of water? A)0)00591 m B)0)272 m C)5)91 m D)272 m

Question

Quizplus · Accepted Answer

Molality (m) is calculated by dividing the moles of solute by the kilograms of solvent. First, calculate the moles of ethanol: 14.6 g / 46.08 g/mol = 0.3169 mol. Then, convert the mass of water to kilograms: 53.6 g = 0.0536 kg. Finally, calculate molality: 0.3169 mol / 0.0536 kg = 5.91 m.
