An ideal solution which is having of 9.0 g of liquid Y, whose molar mass is 30.0 g/mol and 10.0g of liquid X, whose molar mass is 50.0 g/mol. The vapor pressure of pure X and pure Y at 20 degrees Celsius are 40.0 and 70.0 mm Hg, respectively. Determine the weight ratio of X to Y in the first trace of distillate?
