The mass of potassium hydrogen phthalate (KHP) was obtained by weighing it directly using a balance. This is a standard procedure for preparing a primary standard solution. The moles of KHP were then calculated using the measured mass of KHP and its molar mass. The molar mass of KHP (chemical formula KC_8H_5O_4) is 204.24 g/mol. The formula used for calculating moles is: Moles = Mass (g)Molar Mass (g/mol) For example, in Trial 1: Mass of KHP: 0.21900 g Molar Mass of KHP: 204.24 g/mol Moles of KHP (Trial 1) = 0.21900 g204.24 g/mol = 0.00107 mol
