The number of moles of oxygen gas used in the complete combustion of 1 mole of glucose is:
Correct Answer : c ) 6Explanation :
Glucose is a monosaccharide (simple sugar) which contains 6 carbon atoms and an aldehyde group. It is the main sugar found in human blood.
The chemical reaction of the complete combustion of glucose is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O+ Energy
1 mole of glucose requires 6 moles of oxygen to produce 6 moles of carbon dioxide and 6 moles of water.
Mole is the SI unit to measure the amount of any substance. 1 mole is equal to 6.02x1023 of some chemical unit- atoms, molecules, ions or others.
Hence, option (c) is correct.
