A reaction combines 113.4 g of lead(II) nitrate with 45.01 g of sodium hydroxide. Calculate how much lead(II) hydroxide is formed.
Pb(NO3)2(aq) + 2 NaOH(aq) à Pb(OH)2(s) + 2 NaNO3(aq)

Sodium hydroxide reacts with phosphoric acid to give sodium phosphate and water. Calculate the percent when 17.82 g of NaOH is reacted with excess phosphoric acid to yield 15.00 g sodium phosphate.
3 NaOH(aq) + H3PO4(aq) à Na3PO4(aq) + 3 H2O(l)
