Answer: The mole ratio of oxygen to pentane for the combustion of pentane is 8 : 1.

Step-by-step explanation: The given reaction is a type of combustion reaction.

Combustion reaction is a reaction in which a hydrocarbon reacts with oxygen gas to produce water and carbon dioxide gas.

For the reaction of pentane with oxygen, the balanced equation would be:

$C_5H_(12)+8O_2\rightarrow 5CO_2+6H_2O$

In the reaction, 1 mole of
C_5H_(12) reacts with 8 moles of
O_2 gas.

Thus giving us the mole ratio as

Oxygen : Pentane = 8 : 1
