When 3 g of carbon is burnt in 8 g of oxygen, 11 g of carbon dioxide is produced. b) What is the definite proportion by mass in which carbon and oxygen are present in carbon dioxide?
Answers
Answer:
As per the given condition, when 3.0 g of carbon is burnt in 8.00 g oxygen, 11.00 g of carbon dioxide is produced. Therefore, the law of conservation of mass is proved. Then, it also depicts that the carbon dioxide contains carbon and oxygen in a fixed ratio by mass, which is 3:8.

Explanation:
In carbon dioxide, 27.3% of the mass is is carbon, and 72.7% is oxygen. This means that if we had 15 grams of carbon dioxide, it would be composed of 4.09 grams of carbon and 10.91 grams of oxygen. Most compounds have different mass ratios. This is because most compounds have different chemical formulas.
