Answer 1

Answer:

72.7%

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

mass of co2= 1 (c) + 2 (o)

= 1×12+ 2×16

= 12+32

= 44

%of oxygen = 32/44×100

= 72.7%

percentage of Oxygen in the Compound CO2 is 72.7%
