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

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.
