The quantity of tin in a solid can be determined by dissolving it in acid and titrating it with a standard solution of KBrO3.

Hence, if 28.75 mL of 0.1250 M KBrO3 was used to completely react with the dissolved tin mixture, calculate the number of moles of Sn2+ present in the solid.

BrO3 - (aq) + 6H+ (aq) + 6e- → Br- (aq) + 3H2O(l)

Sn4+(aq) + 2e- → Sn2+(aq)
