Question

How many electronic charges from $1$ coulomb?

• A. $9.1\times {10}^{-31}$
• B. $1.6\times {10}^{18}$
• C. $62.5\times {10}^{17}$
• D. $1.76\times {10}^{11}$

Answer 1

Answer: (C)

$62.5\times {10}^{17}$

Let the total electronic charge be n

$1=ne=n\times 1.6\times {10}^{-19}$

$n=62.5\times {10}^{17}$
