If 25.21 ml of naoh sloution is required to react completed with .550 g khp, what is the molarity of the naoh solution

= 0.107 M or 0.107 mol/Liter

Explanation:

The molar mass of KHP is 204.22 g/mol

Therefore;

Moles of KHP = 0.550 g/204.22 g/mol

                      = 0.00269 moles

But, there is an equivalence of 1 : 1 between moles of KHP and moles of NaOH.

Hence; Moles of NaOH is 0.00269 moles

But; Molarity or concentration = Number of moles /Volume in Liters

                                                  = 0.00269 moles/ 0.02521 L

                                                   = 0.107 M or 0.107 mol/L

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
