Total number electrons transferred?

Question

I got this question on my take home exam and I hope somebody can help me really soon. Thanks!

What is the total number of electrons transferred when the equation below is balanced?

Equation: I2+ClO3-+H2O -> IO3-+Cl-+H+ (in acid)

Answer 1

I2  & 10 electrons taken --> 2 (IO3)-

(ClO3)- -> Cl-  & 6 electrons lost

=======================

balance electrons:

3 I2  & 30 electrons taken --> 6 (IO3)-

5(ClO3)- ->5 Cl-  & 30 electrons lost

==============================

Your answer is:30 electrons

===============================

3 I2 & 5 (ClO3)-  & 3 H2O -> 6 (IO3)- & 5 Cl-  & 6 H+
