10.0 mL of 0.0400 M KBrO3 and 10.0 mL 0.100 M HCl is mixed with 10.0 mL of 0.0100 M KI, 10.0 mL 0.00100 M Na2S2O3, 1.0 mL of starch solution, and 10.0 mL H2. What is the concentration of H in this mixture expressed as molarity?

0.0196

Explanation:

The Total volume of the solution = Volume of

= 10 mL + 10 mL + 10 mL+ 10 mL + 1 mL + 10 mL

= 51 mL

The concentration of  

= 0.0196
