| Calculations | Trail 1 | trail 2 | |
| 1. Mass of KHP, g | 0.5038 | 0.5086 | |
| 2. Molar mass of KHP, g/mol | 204.22 | 204.22 | |
| 3. Moles of KHP, mol | Moles= Mass/ Molar mass | 0.00247 | 0.00249 |
| 4. Initial buret reading, mL | 23.51 | 47.1 | |
| 5. final buret reading, mL | 0 | 23.51 | |
| 6.volume of NaOH used, mL | Final -Initial buret reading | 23.51 | 23.59 |
| 7. Moles of NaOH , mol |
1mol of NaOH titrates 1 mol of KHP, moles of NaOH = moles of KHP |
0.00247 | 0.00249 |
| 8. Molarity of NaOH, mol/L |
molarity =moles/ Volume of NaOH in L 1000 mL = 1L |
(0.00247)*1000/23.51 = 0.1047 | 0.1056 |
| 9. Average Molarity of NaOH, mol/L | ( Molarity of NaOH from Trail 1+ Molarity of NaOH from Trail 2)/2 | 0.1051 | |
