A 800.0-mg sample of chromium ore was dissolved and the chromium
oxidized to chromate iron. The solution was treated with 10.00-mL
of 0.200 M AgNO3. The resulting precipitate of Ag2CrO4 was removed
and discarded. The excess AgNO3 required 14.50 mL of 0.1200 M KSCN
for titration. Calculate the % Cr2O3 in the ore.
