Question

The Boiling Point Diagram of Methanol-Water (Figure 5.6) shows Mole Fraction of Water versus Temperature, °C. Using the following atomic weights and the density of methanol of 0.792 g/ml, a 71.7 % v/v methanol in water solution (71.7 ml methanol and 28.3 ml water) is what mole fraction of water? Round to 2 decimal points with no units. Remember that the density of water is defined in the metric system as 1. (C = 12, H = 1, N = 14, O = 16)
