Vedclass · Answer

(C) The number of molecules in $0.1 \ mol$ of gas is $0.1 	imes N_A$. Since the gas is triatomic,each molecule contains $3$ atoms. Number of atoms = (Number of molecules) $	imes$ (Atomicity) Number of atoms = $(0.1 	imes 6.022 	imes 10^{23}) 	imes 3$ Number of atoms = $0.3 	imes 6.022 	imes 10^{23} = 1.8066 	imes 10^{23}$ Rounding to the nearest provided option,the answer is $1.806 	imes 10^{23}$.

The number of atoms present in $0.1 \ mol$ of a triatomic gas is: $(N_A = 6.022 \times 10^{23} \ mol^{-1})$
