Question

how many moles of ethane are required to produce 44g of CO2 after the combustion of ethane?​???​

Answer 1

Reaction for the combustion of the Ethane is ⇒

___________________________

2C₂H₆ + 7O₂ ----------→ 4CO₂ + 6H₂O

___________________________

From this reaction, 

∵ 4 mole of the Carbon dioxide is prepared by the 2 mole of the Ethane.

∴ 1 mole of the Carbon dioxide is prepared by the 0.5 mole of the Ethane.

∵ 1 mole of the Carbon dioxide = 44 g. 

∴ Moles of the Ethane required for the combustion is 0.5 moles.

Answer 2

Answer:

mass of etahne = 30

mass of co2 = 44

no of moles = 30/44

0.6818 moles
