Question

The combustion of ethane (C2H6) produces carbon dioxide and steam.

2C,H, (g) + 702(g) — 4CO2(g) + 6H2O(g)
How many moles of Co, are produced when 5.55 mol of ethane is burned in an excess of oxygen?
moles of CO2:

Answer 1

Number of moles of CO₂ produced = 11.1 mol

Step-by-step explanation:

Given data:

Mass of ethane = 5.55 mol

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O

Now we will compare the moles of ethane and carbondioxide.

C₂H₆ : CO₂

2 : 4

5.55 : 4/2×5.55 = 11.1 moles

Number of moles of CO₂ produced = 11.1 mol
