What charge is needed to deposit 0.1 mol of copper from solution? ( C/mol)
Answer and explanation
Correct answer: A. 19 300 C
- Step 1: Each copper ion needs 2 electrons, so mol. Step 2. C. Answer: 19 300 C. Why not the others: 9 650 C ignores the 2+ charge; 96 500 C is one mole of electrons; 1 930 C is a power-of-ten slip.
