Answer:
0.00375 moles OF KHP
Explanation:
Equation of reaction of NaOH and KHP :
KHC₈H₄ O₄(aq) + NaOH(aq) → NaKC₈H₄O₄(aq) + H₂O(l)
the reaction required 25ml
Molarity = no of mole / volume in liters
no of moles = Molarity × volume in liters
no of moles of NaOH = 0.150 × (25/1000) = 0.00375 moles
using the balanced equation above
1 mole of NaOH requires 1 mole of KHP
therefore
0.00375 mole of NaOH will require 0.00375 mole KHP.
