Question

Suppose a current of 0.880 A flows through a copper wire for 132. seconds. Calculate how many moles of electrons travel through the wire. Be sure your answer has the correct unit symbol and the correct number of significant digits.

Answer 1

Answer:

0.00120 moles

Explanation:

Given that:-

Current, I = 0.880 A

Time, t = 132 seconds

Considering:-

$I=\frac{Charge,\ q}{t}$

$0.880\ A=\frac{q}{132\ sec}$

Charge=0.880*132 C = 116.16 C

Also, 1 mole of electrons contain a charge of 96500 C

Thus, Moles = $\frac{116.16}{96500}=0.00120$ moles
