Answer 2

Mass of CO₂ = 33 g

Further explanation  

Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.  

If O₂ is insufficient there will be incomplete combustion produced by CO and H and O  

Reaction

CH₄ + 2O₂⇒CO₂ + 2H₂O

mol CH₄ :

$\tt =\dfrac{16}{16}=1$

mol O₂ :

$\tt =\dfrac{48}{32}=1.5$

A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients

$\tt CH_4:O_2=\dfrac{1}{1}:\dfrac{1.5}{2}=1:0.75$

Because O₂ ratio smaller then O₂ becomes the limiting  reactants

So mol CO₂ from limiting reactants

mol CO₂ :

$\tt \dfrac{1}{2}\times 1.5=0.75$

mass CO₂ :

$\tt mass=mol\times MW=0.75\times 44=33~g$
