What is the mass of sodium bromate and molarity of solution to prepare 85.5 mL of 0.672N solution when half cell reactions are? -

\text{BrO}_3^- + 6\text{H}^+ + 6\text{e}^- \longrightarrow \text{Br}^- + 3\text{H}_2\text{O}

. -

2\text{BrO}_3^- + 12\text{H}^+ + 10\text{e}^- \longrightarrow \text{Br}_2 + 6\text{H}_2\text{O}
