Vedclass · Answer

(D) Step $1$: Calculate the number of moles of $CO_2$ using the given molar volume at $	ext{STP}$.Number of moles $= \frac{	ext{Given Volume}}{	ext{Molar Volume}} = \frac{45.42 \ L}{22.71 \ L \ mol^{-1}} = 2 \ mol$.Step $2$: Calculate the number of molecules using Avogadro's number $(N_A = 6.022 	imes 10^{23} \ mol^{-1})$.Number of molecules $= 	ext{moles} 	imes N_A = 2 \ mol 	imes 6.022 	imes 10^{23} \ mol^{-1} = 1.2044 	imes 10^{24}$ molecules.

What is the number of $CO_2$ molecules in $45.42 \ L$ at $\text{STP}$? (Consider molar volume of gas at $\text{STP} = 22.71 \ L \ mol^{-1}$)
