Vapor Pressure Calculation?

Calculate the vapor pressure of a solution containing 26.4 g of glycerin (C3H8O3) in 132 mL of water at 30.0 degrees C. The vapor pressure of pure water at this temperature is 31.8 torr. ume that glycerin is not volatile and dissolves molecularly (i.e., it is not ionic) and use a density of 1.00 g/mL for the water.
