mols KHP = grams/molar mass = ?
mols NaOH in a 1:1 reaction = mols KHP.
Then M NaOH = mols NaOH/ L NaOH = ?
#4. mols NaOH = M x L = ?
mols KHP = mols NaOH
grams KHP = mols KHP x molar mass KHP.
%KHP = (grams KHP/mass sample)*100 = ?
Given the following equation and information answer the following questions,
KHC8H4O4 (aq) + NaOH(aq) > KNaC8H4O4 (aq) + H2O(l)
3. What is the molarity of a NaOH solution if 26.50 mL of it is required to neutralize 0.4150 g of pure KHP? (3 points)
4. What is the percentage of KHP in an impure sample of KHP that weighs 0.4200 g and requires 14.00 mL of 0.098 M NaOH to neutralize it? (4 points)
