## Homework Statement

Current passes through a solution of sodium chloride. In 1.00 second, 2.68 x 10^16 Na+ ions arrive at the negative electrode and 3.92 x 10^16 Cl- ions arrive at the positive electrode.

What is the current passing between the electrodes?

Express your answer in milliamperes to three significant figures.

Part B

What is the direction of the current?

~away from the negative electrode or

~toward the negative electrode

## Homework Equations

I = Q/t

## The Attempt at a Solution

the difference between 2.68x10^16 and 3.92x10^16 as a Na+ ion and Cl- ion carry precisely one electric charge each, and the charge of an electron is 1.60 x 10^-19 C

I = Q/t

I = (1.60 x 10^-19 )/1

I = 1.60 x 10^-19 A = 1.60 x 10^-16 mA

am I right?

Part B

Conventional current was defined early in the history of electrical science as a flow of positive charge, so it would be towards the negative electrode?
