How many moles of electrons are produced from a current of 15.6 A in 3.20 h?

Thank you for the opportunity to help you with your question!

1 Ampere is 1 Coulomb per sec

Thus 15.6 for 3.20 hours = 11520 seconds wild yield 179712 coulomb

1 Coulomb is 6.241×10^{18} times the elementary charge (the one electron charge)

So the number of electrons will be 179712 * 6.241 * 10^18 = 11.21 10^4 * 10^18 = 11.21* 10^23 electrons

1 mol of electrons is equivalent to that many electrons as the avocado number meaning

1 mol is 6.022×10^{23 electrons }So the number of moles we will have will be : n = 11.21 * 10^23/ 6.022 10^ 23 = 1.86 molCorrect answer is d. 1.86 mol

1 mol is 6.022×10^{23 electrons }

So the number of moles we will have will be : n = 11.21 * 10^23/ 6.022 10^ 23 = 1.86 mol

Correct answer is d. 1.86 mol
