The reaction produces 6 g of carbon dioxide.

The word equation is

methane + oxygen → carbon dioxide + water

 12.2 g    +    4 g     →            x g          +  20 g

The <em>Law of Conservation of Mass</em> tells us the total mass of the reactants must equal the mass of the products. Then

12.2 g + 14 g =<em> x</em> g + 20 g

<em>x</em> = 12.2 + 14 – 20 = 6

The mass of carbon dioxide is 6 g.

<em>Note</em>: The answer can have <em>no decimal places</em> because you gave none for the masses of oxygen and water.
