aoult's law can be used to determine the molar mass of an unknown substance based on the vapor pressure of a solution. This problem will walk you through the steps required. A chemist wants to determine the molar mass of a naturally occurring substance isolated from spearmint. She adds 5.131 g of this substance to 25.00 g of acetone (C3H6O; molar mass 58.08 g/mol). The vapor pressure of the solution is determined to be 0.2444 atm at 25°C. If the vapor pressure of pure acetone at this temperature is 0.2630 atm, what is the mole fraction of the solvent in this solution? Give your answer to four significant digits. Using your answer from Part 1, calculate the moles of solute present in the solution. Give your answer to three significant digits.
