The number moles of carbon dioxide 31.2 moles will be produced when 10.4 mol of propane gas is burned in excess oxygen.
A mole would be the amount of a material that includes exactly 6.02214076 × [tex]10^{23}[/tex] of the particular chemical elementary constituents.
It is known that the formula of propane is [tex]C_{3}H_{8}[/tex].
The chemical reaction of propane.
[tex]C_{3}H_{8}[/tex] + [tex]5O_{2}[/tex] → [tex]3CO_{2} +4H_{2}O[/tex]
It can be understand that, the ratio of propone and carbon di-oxide is 1:3.
The moles of propane = 10.4 mol
So, number of moles of [tex]CO_{2}[/tex] = 10.4 mol × 3 =31.2 mol.
Therefore, the number of moles of carbon di-oxide will be 31.2
Hence, the correct answer will be option (C).
