Vedclass · Answer

(C) The number of molecules is proportional to the number of moles $(n)$.$(A)$ $n = \frac{0.4 	ext{ g}}{2 	ext{ g/mol}} = 0.2 	ext{ mol}$.$(B)$ $n = \frac{2 	ext{ g}}{32 	ext{ g/mol}} = 0.0625 	ext{ mol}$.$(C)$ At $STP$, $1 	ext{ mol}$ occupies $22.4 	ext{ dm}^3$. So, $n = \frac{8 	ext{ dm}^3}{22.4 	ext{ dm}^3/	ext{mol}} \approx 0.357 	ext{ mol}$.$(D)$ $n = \frac{2 	ext{ dm}^3}{22.4 	ext{ dm}^3/	ext{mol}} \approx 0.089 	ext{ mol}$.Comparing the values, $0.357 	ext{ mol}$ is the highest. Thus, option $(C)$ contains the maximum number of molecules.
