The formula of propane is C3H8. The reaction equation is C3H8 + 5O2 = 3CO2 + 4H2O. So the ratio of mol number of propane and CO2 is 1:3. So the CO2 has 10.4*3=31.2 mol. So the answer is c.

The number moles of carbon dioxide 31.2 moles will be produced when 10.4 mol of propane gas is burned in excess oxygen.

What is moles?

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).
