Answer:
28.836 C
Explanation:
Data provided in the question:
Total number of electrons passed through the pocket calculator during a full day's operation = 1.80 × 10²⁰
Now,
We know that the charge of an electron is 1.602 × 10⁻¹⁹ C
Therefore,
The total charge moved through the calculator during the operations
= Total number of electrons passed × Charge of an electron
= (1.80 × 10²⁰) × ( 1.602 × 10⁻¹⁹ )
= 28.836 C
