(i) What is the weight of sodium bromate and molarity of solution necessary to prepare 85.5 mL of 0.672 N solution when the half-cell reaction is
`BrO_(3)^(-) + 6H^(+) + 6e to Br^(-) + 3H_(2) O`?
(ii) What would be the weight as well as molarity if the cell reaction is
`2BrO_(3)^(-) + 12H^(+) + 10e to Br_(2) + 6H_(2) O`?

Explanation

(i) 1.4479 g, 0.112 M (ii) 1.7236 g, 0.134 M
