Two solvents A and B are mixed together. if the molecular weight for A is 50.46 g/mol and the molecular weight for B is 115.6 g/mol. A solution is made by mixing 2.00 g of each organic volatile solvent at 0.00 °C. If the partial pressure of the organic solvent A in the mixture was exactly 125 torr. What is the total pressure of the solution?

Question
Two solvents A and B are mixed together. if the molecular weight for A is 50.46 g/mol and the molecular weight for B is 115.6 g/mol. A solution is made by mixing 2.00 g of each organic volatile solvent at 0.00 °C. If the partial pressure of the organic solvent A in the mixture was exactly 125 torr. What is the total pressure of the solution?
Expert Solution
Introduction
Use Dalton's law to find the total pressure of the solution.
P = PA + PB
PA = 125 torr
MA=50.46 g/mol
MB=115.6g/mol
Also PA = PtotalXA
where XA is the mole fraction of component A
