A current passes through a solution of sodium chloride. In 1.00 s, 2.68×10¹⁶ Na+ ions arrive at the negative electrode and 3.92×10¹⁶ Cl⁻ ions arrive at the positive electrode. What is the total charge that passes through the solution in this time?

Final answer:

The total charge that passes through the solution in 1 second can be calculated by multiplying the number of ions by the elementary charge. In this case, the total charge is 10.56 x 10^10 C.

Step-by-step explanation:

The total charge that passes through the solution can be calculated using the formula Q = n * e, where Q is the total charge, n is the number of ions, and e is the elementary charge. In this case, we have 2.68×10¹⁽ Na+ ions and 3.92×10¹⁽ Cl- ions. Since Na+ and Cl- ions both have a charge of 1, the total number of charges is equal to the sum of the number of Na+ and Cl- ions. Therefore, the total charge passing through the solution is given by:

Q = (2.68×10¹⁽ + 3.92×10¹⁽) * e

Q = 6.60×10¹⁽ * e

Using the value of the elementary charge e = 1.6×10⁽⁸ C, we can calculate the total charge:

Q = 6.60×10¹⁽ * 1.6×10⁽⁸ C

Q = 10.56×10⁽ C

Therefore, the total charge that passes through the solution in 1.00 s is 10.56×10⁽ C.
