Question

The charge on $500cc$ of water due to protons will be

• A. $6.0\times 10^{27}C$
• B. $2.67\times 10^{7}C$
• C. $6\times 10^{23}C$
• D. $1.67\times 10^{23}C$

Answer 1

Answer: (B)

$Q=ne$, where $n=$ number of moles $\times 6.02\times 10^{23}\times 10$
$\Rightarrow Q=\frac{500}{18}\times 6.02\times 10^{23}\times 10\times 1.6\times 10^{-19}$
$=2.67\times 10^{7}C$
