If 33.0 mL of 0.002 M aqueous H3PO4 is required to neutralize 28.0 mL of an aqueous solution of NaOH, determine the molarity of the NaOH solution.

H3PO4 + 3NaOH ==> 3H2O + Na3PO4

mols H3PO4 = M x L = ?
mols NaOH = mols H3PO4 x (3 mols NaOH/1 mol H3PO4) = moles H3PO4 x 3 = ?

M NaOH = mols NaOH/ L NaOH
