Based on the provided image and calculations, there is no mass of 0.49 g used in calculating the moles of potassium hydrogen phthalate (KHP). The masses of KHP used in the calculations were: Trial 1: 0.21900 g Trial 2: 0.28900 g Trial 3: 0.22000 g These masses were then divided by the molar mass of KHP (204.24 g/mol) to obtain the moles of KHP. For example, using the mass from Trial 1: Moles of KHP = 0.21900 g204.24 g/mol = 0.00107 mol
