Question

formula for KHP is KC8H5O4

Answer 1

Answer #1

Answer

0.1191M

Explanation

The reaction between KHP and NaOH is 1:1molar

KHP(aq)+ NaOH(aq) -----> NaKHP(aq) + H2O(l)

mole = mass/molar mass

moles of KHP = 0.400g /204.22g/mol = 0.001959mol

0.001959moles of KHP react with 0.001959moles of NaOH

moles of NaOH present in the 16.45ml of NaOH solution = 0.001959mol

molarity = number of moles of solute per liter of solution

molarity of NaOH = (0.001959mol/16.45ml) ×1000ml = 0.1191M
