Q2 / 180 · COMEDK 2020 · Chemistry
The number of gram molecules of chlorine in $6.02 \times 10^{25}$ hydrogen chloride molecules is
- A5
- Correct answerB50
- C100
- D10
Solution
Number of gram molecules of chlorine in $\mathrm{HCl}$
$$
\begin{gathered}
=\frac{\text { number of }}{}=\frac{6.02 \times 10^{25}}{6.02 \times 10^{2}} \\
=\frac{100}{2}=50
\end{gathered}
$$
Hence, the correct answer is option: 'B'.
