Question

How much mass of carbon dioxide gas will contain 1 gm-atom of oxygen?

Answer 1

Answer:

This means that 1 mole of carbon dioxide has a mass of 44.01 g . Oxygen has a molar mass of 16.0 g mol−1 , so 1 mole of oxygen atoms has a mass of 16.0 g . Therefore, 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.

Answer 2

Explanation: We know that in CO2 we have C:O2 i.e. 12: 32 by mass means 3:8 of carbon dioxide by mass. ( 3×5) . Hence 3:8 is 15:40 , So, 15g + 40g = 55g.
