44 gm of CO2 will be produced and the law of definite proportions is applied in the given case.
- For case 1st:
The ratio of mass of carbon to oxygen = 3:8
- For case 2nd:
The ratio of mass of carbon to oxygen = 12:32 = 3:8
- As the ratio is the same, it means that the law of definite proportions is followed here.
- Also, the mass of both carbon and oxygen adds up.
- So, the mass of CO2 = 12 + 32 = 44 gm
