How many moles of carbon dioxide are produced when 5.12 mol of propane gas is burned in excess oxygen? c3h8(g) + 5o2(g) → 3co2(g) + 4h2o(l)

15.4 mol CO₂

Explanation:

5.12 mol C₃H₈ × (3 mol CO₂ / mol C₃H₈) ≈ 15.4 mol CO₂

15.36 moles of carbon dioxide are produced when 5.12 mol of propane gas is burned in excess oxygen

Explanation:

The Balanced Chemical equation is :

Mole ratio of is 1 : 3

That is, 1 mole of propane gas produces 3 moles of carbon dioxide gas.

Using mole ratio we can solve this  

is produced.

(Answer)

Please note  :

To convert moles to mass, we multiply by molar mass  

To convert mass to moles, we divide by molar mass

Molar mass is the mass of 1 mole of the substance

For example molar mass of is

(we just add the atomic mass of the atoms to get the molar mass of the substance)
