The gas showing least adsorption on a definite amount of charcoal is

$$100 \mathrm{~mL}$$ of $$5 \%\,(\mathrm{w} / \mathrm{v})$$ solution of $$\mathrm{NaCl}$$ in water was prepared in $$250 \mathrm{~mL}$$ beaker. Albumin from the egg was poured into $$\mathrm{NaCl}$$ solution and stirred well. This resulted in a/an :
