Question

The combustion of ethane (C 2 H 6 ) produces carbon dioxide and steam.

2C 2 H 6 (g)+7O 2 (g) 4CO 2 (g)+6H 2 O(g)

How many moles of CO 2 are produced when 5.95 mol of ethane is burned in an excess of oxygen?

Answer 1

CO₂ produced : 11.92 moles

Further explanation

Reaction

2C₂H₆ (g)+7O₂ (g) ⇒4CO₂ (g)+6H₂O(g)

mol ratio C₂H₆ : CO₂ = 2 : 4

moles of CO₂ :

`\tt (4)/(2)* 5.95=11.92~moles`
