Explanation:

Ethane will burn in oxygen to form carbon dioxide and water according to the following balanced equation:

$2C_2H_6+7O_2 ---> 4CO_2+6H_2O$

<em>From the equation, it means that for every one mole of ethane, three and a half moles of oxygen gas are required for complete combustion into carbon dioxide and water. Two and three moles of carbon dioxide and water would be produced respectively for every one mole of ethane that burns in three and a half moles of oxygen gas. </em>
