  If 1 g of each of the following gases are taken at STP, which of the gases will occupy (a) greatest volume (b) smallest volume? \[CO,C{{H}_{4}},{{H}_{2}}O,NO\]                

Answer:

     

Gas	Number of moles	Volume
\[CO\]	\[\frac{1}{28}\]	\[\frac{1}{28}\times 22.4=0.8L\]
\[C{{H}_{4}}\]	\[\frac{1}{16}\]	\[\frac{1}{16}\times 22.4=1.4L\] \[(Maximum)\]
\[{{H}_{2}}O\]	\[\frac{1}{18}\]	\[\frac{1}{18}\times 22.4=1.24L\]
\[NO\]	\[\frac{1}{30}\]	\[\frac{1}{30}\times 22.4=0.75L\] \[(Minimum)\]
