Preparation and Standardization of 0.1M NaOH Solution

CH3CO2H + NaOH CH3CO2– Na+ + H2O

Weight of KHP (g) = 2.100
Volume of KHP (ml) = 100.00
Molecular weight of KHP = 204.23 g/mol
Molarity of KHP (M) = 100 / 204.23 = 0.01028
Volume (L) of NaOH used in Trial 1: 0.02755
Volume (L) of NaOH used in Trial 2: 0.02965
Volume (L) of NaOH used in Trial 3: 0.02905

Molarity of NaOH(M) of Trial 1: 0.01028 / 0.02755 = 0.373
Molarity of NaOH(M) of Trial 2: 0.01028 / 0.02965 = 0.347
Molarity of NaOH(M) of Trial 3: 0.01028 / 0.02905 = 0.354

Question: I would like to know is the answer of Molarity of NaOH(M) correct? thanks
