Question

When 3.00 g of carbon is burnt in 8.00 g
oxygen, 11.00 g of carbon dioxide is produced. What
mass of carbon dioxide will be formed when 3.0 g of
carbon is burnt in 50.00 g of oxygen? Which law of
chemical combination will govern your answer?
​

Answer 1

Answer:

When 3.0 g of carbon is burnt in 8.00 g of oxygen, 11.00 g of carbon dioxide is produced.

Thus carbon and oxygen are combined in the ratio of 3 : 8 to give 11g of carbon dioxide .

Hence for 3 g of carbon and 50 g of oxygen, 8 g of oxygen is used and 11g of carbon is formed while 42 g of oxygen is left unused. This chemical combination is governed by law of definite proportions.
