The percentage of carbon in carbon dioxide, CO2, is about 27%. The percentage of oxygen (to the nearest whole number) in CO2 is

Percentage of oxygen = 73%

Explanation:

Given data:

Percentage of C in CO₂ = 27%

Percentage of O₂ in CO₂ = ?

Solution:

The percentage of carbon in carbondioxide is 27% then the percentage of oxygen will be calculated by subtracting the percentage of carbon from 100.

Percentage of oxygen = 100 - percentage of carbon

Percentage of oxygen = 100-27

Percentage of oxygen = 73%
