I don't even know what equation to use!
In an ionic solution, 5.0*10^15 positive ions with +2e charge pass to the right each second while 6.0*10^15 negative ions with charge e pass to the left. What is the magnitude of current in the solution? (5.0*10^15)*(2*1.6*10^19)  (6.0*10^15)*(1.6*10^19)=8.3*10^4

my calculation was wrong, when I recalculated it i got 6.4E4, and that was still wrong
What equation should i use?

Current in a solution
There must be two different solutions in the electrolyte. So when +2e charge from one solution moving toward right,2e charge is moving towards left. This adds to e charge from the second solution. So net flow of charge is 3e towards left.
