Vedclass · Answer

(A) At $S.T.P.$ (Standard Temperature and Pressure),the molar volume of an ideal gas is $22.4 \, litres$. According to Avogadro's hypothesis,$1 \, mole$ of any gas contains $6.023 	imes 10^{23}$ molecules. Therefore,$22.4 \, litres$ of gas contains $6.023 	imes 10^{23}$ molecules. To find the number of molecules in $1 \, litre$,we divide the total number of molecules by the molar volume: Number of molecules $= \frac{6.023 	imes 10^{23}}{22.4} \approx 2.68 	imes 10^{22}$ molecules.
