Chapter 12, Problem 12PE

Water freezes at a lower temperature when it contains solutes. To study the effect of methanol on the freezing point of water, we might begin by preparing a series of solutions of known molalities. Calculate the number of grams of methanol $\left({\text{CH}}_{\text{3}}\text{OH}\right)$ needed to prepare a series of solutions from 0.050 to 0.250 m in 0.050 m increments. For each solution use 200.0 g of water.
