mols KOH = M x L = ?
Using the coefficients in the balanced equation, convert mols KOH to mols H3PO4.
Then M H3PO4 = mols H3PO4/L H3PO4.
A solution of 0.316 M KOH is used to neutralize 16.0 mL H3PO4 solution
H3PO4(aq) + 3KOH(aq) �¨ K3PO4(aq) + 3H2O(l)
If 30.3 mL KOH solution is required to reach the endpoint, what is the molarity of the H3PO4 solution?
Molarity = ____________
