1) Ivanka brings a 750 ml cup of coffee to class, if she drinks the cup of coffee how many moles of hydrogen has she consumed? (Assume the pH of the coffee is 5.) 2) How many hydrogen ions has she consumed? 3) Instead Rudy consumes 500 ml of orange juice (pH 3.3), who has consumed more hydrogen ions?
