An aqueous solution of glycerol, C₃H₈O₃ is prepared by adding 150.0 g of glycerol to 200.0 g of water. What is the mole fraction of glycerol in the final solution?

Question

Quizplus · Accepted Answer

To find the mole fraction of glycerol, first calculate the moles of glycerol and water. Moles of glycerol = 150.0 g / 92.09 g/mol = 1.629 mol. Moles of water = 200.0 g / 18.02 g/mol = 11.10 mol. Mole fraction of glycerol = moles of glycerol / (moles of glycerol + moles of water) = 1.629 / (1.629 + 11.10) = 0.128.
