Question

Which has the maximum number of molecules among the following?

• A. $48\text{g}{O}_3$
• B. $64\text{g}S{O}_2$
• C. $44\text{g}C{O}_2$
• D. $8\text{g}{H}_2$

Answer 1

The correct option is D $8\text{g}{H}_2$

$\begin{array}{cc}& \text{No. of molecules}\\ \text{Moles of}C{O}_2=\frac{44}{44}=1& N_A\\ \text{Moles of}{O}_3=\frac{48}{48}=1& N_A\\ \text{Moles of}{H}_2=\frac{8}{2}=4& 4N_A\\ \text{Moles of}S{O}_2=\frac{64}{64}=1& N_A\end{array}$

Hence, option (c) is correct.
