A student was given only one graduated cylinder to use for this experiment. ? after using it to measure 50.0mL of the assigned acid, the student failed to rinse or dry the cyclinder before measuring out the 50.5mL of the base. would the calculated H neutzn be higher, lower, or the same as the literature H neutzn? briefly explain this difference as a result of using only one graduated cylinder for the experiment
