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
