A gaseous mixture contains 14 g of $N_{2}$, 8.0 g of $O_{2}$ and 8.0 g of $H_{2}$. Total number of molecules present in the mixture is ($N_{A}$ = Avogadro number) (At.wt; H=1, N=14, O=16)}
Show Hint
Calculate moles for each component individually before summing them up to find the total molecular count.
