Question

How many molecules of CO2 is needed to produce 10 molecules of C6H12O6?

Answer 1

Answer:

6 molecules of carbon dioxide are required, one for each carbon atom in glucose. 6 molecules of oxygen are produced as a by product of water oxidation.

Answer 2

One molecule of C₆H₁₂O₆(Glucose) contains the following: 6 atoms of carbon,  12 atoms of hydrogen, and 6 molecules of oxygen.

One molecule of CO₂ contains the following: 1 atom of carbon and 2 atoms of oxygen.

So, in 10 molecules of glucose, the number of carbon atoms will be = Carbon atoms in one glucose molecule x 10

No. of carbon atoms in 10 glucose molecules = 6 x 10

                                                                            = 60

No of CO₂ molecules needed for 10 glucose molecules = No. of carbon atoms in 10 glucose molecules / No. of carbon atoms in one glucose molecule

No of CO₂ molecules needed for 10 glucose molecules = 60/2

                                                                                             = 30

Therefore, 30 molecules of CO₂ are required for producing 10 molecules of C₆H₁₂O₆(Glucose).
