At a certain temperature the vapor pressure of pure benzene (C6H6) is measured to be 375 , mmHg. Suppose a solution is prepared by mixing 52.7 g of bentene and 148. 8 of heptane (C7H16). Calculate the partial pressure of benzene vapor above this solution. Be sure your answer has the correct number of significant digits. Note for advanced students: you may assume the solution is ideal
