Safrole is used as a topical antiseptic. Calculate the vapor pressure of a solution prepared by dissolving 0.75 mol of safrole in 950 g of ethanol (? = 46.07 g/mol). P$\degree$_ethanol = 50.0 torr at 25$\degree$C. A) 1.8 torr B) 11 torr C) 15 torr D) 40 torr E) 48 torr

The vapor pressure of the solution can be calculated using Raoult's Law: P_solution = X_solvent * P°_solvent. First, calculate the moles of ethanol: 950 g / 46.07 g/mol = 20.62 mol. The mole fraction of ethanol (X_ethanol) is 20.62 / (20.62 + 0.75) = 0.965. Then, P_solution = 0.965 * 50.0 torr = 48.25 torr, which rounds to 48 torr.
