Mass of CO₂ = 33 g
<h3>Further explanation </h3>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 :
mol O₂ :
A method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients
Because O₂ ratio smaller then O₂ becomes the limiting reactants
So mol CO₂ from limiting reactants
mol CO₂ :
mass CO₂ :
Answer:
<h3>The answer is 3.44 g/cm³</h3>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 17.2 g
volume = 5 cm³
We have
We have the final answer as
<h3>3.44 g/cm³</h3>Hope this helps you
