Methyl-t-butyl ether, C5H12O, is added to gasoline to promote cleaner burning. How many moles of oxygen gas, O2, are required to burn 1.0 mol of this compound completely to form carbon dioxide and water?
Methyl-t-butyl ether is a hydrocarbon. So when it reacts with Oxygen it will produce `CO_2` and `H_2O` . The combustion reaction can be given as follows.
`C_5H_12O+15/2O_2 rarr 5CO_2+6H_2O`
`C_5H_12O:O_2 = 1:15/2`
Since we have only one mole of Methyl-t-butyl ether we need 15/2 moles of ` O_2` to react with this compound.
So the oxygen required for the reaction is 15/2 moles.
