Question

How many electrons are necessary to produce 1.0 C of negative charge? (e = 1.60 × 10-19 C) Group of answer choices

Answer 1

6.25×10¹⁹ e⁻

Step-by-step explanation:

Let's apply a rule of three:

1 e⁻ has 1.60×10⁻¹⁹ C

There, we can think:

1.60×10⁻¹⁹ C of charge are made by 1 e⁻

If we want to produce 1 C, we would need ( 1 . 1) / 1.60×10⁻¹⁹

= 6.25×10¹⁹ e⁻
