(D) $Step \ I$: Calculate the number of oxygen atoms in $22 \ g$ of $CO_2$.Molar mass of $CO_2 = 12 + 2 	imes 16 = 44 \ g/mol$.Moles of $CO_2 = \frac{22 \ g}{44 \ g/mol} = 0.5 \ mol$.Since $1 \ mol$ of $CO_2$ contains $2 \ mol$ of oxygen atoms,$0.5 \ mol$ of $CO_2$ contains $0.5 	imes 2 = 1 \ mol$ of oxygen atoms.$Step \ II$: Calculate the weight of $CO$ containing $1 \ mol$ of oxygen atoms.Molar mass of $CO = 12 + 16 = 28 \ g/mol$.$1 \ mol$ of $CO$ contains $1 \ mol$ of oxygen atoms.Therefore,the weight of $CO$ required is $28 \ g$.

Find the weight in grams of carbon monoxide $(CO)$ that contains the same number of oxygen atoms as are present in $22 \ g$ of carbon dioxide $(CO_2)$.
