please help me and round answer to 3 significant digits

At a certain temperature the vapor pressure of pure methanol (CH,OH) is measured to be 239, torr Suppose a solution is prepared by mixing 114 moethanol and 114. g of acetone (CH),CO) Calculate the partial pressure of methanol vapor above this solution. Round your answer to 3 significant digits Note for advanced students you may assume the solution is ideal X 2
