Question

Calculate the number of oxygen atoms present in 100 gram of carbon dioxide carbon oxide

Answer 1

For 100% of carbon dioxide,there is 72.7% of oxygen.
Then,
Carbon dioxide = 100 gram
Oxygen = 72.7%of 100g
=72.7 grams

Answer 2

Answer:

Oxygen has a molar mass of 16.0 g mol−1 , so 1 mole of oxygen atoms has a mass of 16.0 g .

, carbon dioxide has a percent composition of 72.7% oxygen, i.e. for every 100 g of carbon dioxide you get 72.7 g of oxygen.
