Question

a solution of 12.6 g of a non-electrolyte compound in 75.0 g of water freezes at -3.26 °C. What is the molecular mass of the solute?

Answer 1

First, scale up your solution to # of grams of compound in 1000 g water. Call this "A" Now, recall the molal constant for freezing point depression. Divide 3.26 by that value, this gives you the # of moles of your compound in solution. Call this "B". Then you can compute A/B
