A beaker contains 10.0 g of water (H2O) and 10.0 g of ethanol (C2H5OH). (This setup should seem familiar.) What is the mole percent of water in solution? At 25 \deg C, the vapor pressure of water is 23.8 torr, and the vapor pressure of ethanol is 60.0 torr. What is the vapor pressure of the solution? Assume ideal solution behavior (quite an assumption for water and ethanol). Do not include units in answer. During the second problem today, we identified the mole percent of water in this solution was 71.9
