Calculations


In order to calculate the unknown molarity of KHP, this formula must be used.

     Molarity= #moles KHP
                 ml NaOH 
To find the molar mass of KHP, you must add the molar masses 
of K,(39.1)+H,(1.01)+P,(31.0). 39.1 1.01 +31.0 71.11grams mole To find the # of moles, you must multiply the grams KHP by the grams per mole .704 x 1 mole = .0099 moles 71.1 grams .714 x 1 mole = .0100 moles 71.1 grams Finally, finish the equation. Molarity = .0099 moles = .000505 19.6 ml Molarity = .0100 moles = .000510 19.6 ml
