The number of moles of oxygen gas used in the complete combustion of 1 mole of glucose is:

Explanation:

• Combustion is a chemical reaction in which a substance reacts quickly with oxygen and produces heat.
• The original substance is referred to as the fuel, and the source of oxygen is referred to as the oxidizer.
• The fuel can take the form of a solid, liquid, or gas.

The Combustion equation for glucose is given as follows;

C₆H₁₂O₆ +6O₂ → 6CO₂  + 6H₂O

From the above balanced equation we can see that,

For complete combustion of 1 mole of glucose we need 6 mole of oxygen gas.

Hence, The number of moles of oxygen gas used in the complete combustion of 1 mole of glucose is 6
