A 5.351 g solid sample containing only KNO₂ (FW = 85.104 g/mol) and KNO3 (FW = 101.103 g/mol) is dissolved in 500.0 mL of water. A 50.00 mL aliquot of the solution is treated with 48.00 mL of 0.1171 M Ce** in strong acid to oxidize the nitrite (NO₂) ion and form the nitrate (NO3) ion. After 5 minutes, the excess Ce4+ is back-titrated with 33.57 mL of 0.04141 M Fe²+. Calculate the mass percent of KNO₂ in the solid.
