What is the magnitude of the current in this ionic solution?

Click For Summary
SUMMARY

The magnitude of current in the ionic solution is calculated by considering the flow of both positive and negative ions. In this case, 3.93×1015 positive ions with a charge of +2e and 9.01×1015 negative ions with a charge of -e are involved. The correct formula for current (I) is I = Ch in Q / Ch in T, where the charge of the positive ions must be multiplied by two. The final calculation should reflect the total charge contributed by both types of ions.

PREREQUISITES
  • Understanding of ionic solutions and ion charge
  • Familiarity with the concept of electric current
  • Knowledge of basic algebra for calculations
  • Proficiency in using scientific notation
NEXT STEPS

Current...please help!

Homework Statement



In an ionic solution, 3.93×10^15 positive ions with charge +2e pass to the right each second while 9.01×101^5 negative ions with charge -e pass to the left. What is the magnitude of current in the solution?

Homework Equations



I = Ch in Q / Ch in T

The Attempt at a Solution



So I did...
R = 1.6x10^-19 * 3.93x10^15 / 1
R = -1.6x10^-19 * 9.01x10^15 / 1
and then I added them...what am I doing wrong?

You forgot to multiply by two here.
