Expert Answer:

                  According to Raoult’s law, for a dilute solution
                                                                                                                                                             
                            P0- P      =      w x M  
                        ---------            -----------
                             P0                  W x M’         
 
       or                                                                                                                                                     
                       23.75- P      =      5 x 18  
                        ---------            --------------       = .015
                        23.75                  100 x 60                                                                                                                                    
              
 
P = 23.75- (23.75 x .015 ) = 23.39 mm Hg
