the atmosphere has approximately 78% nitrogen and 21% oxygen. all other gases, like argon and carbon dioxide make up what percentage of the atmosphere? 70% 1%

Answer

Explanation:

Step1: Consider total percentage as 100%

Let the total percentage of atmosphere be 100%.

Step2: Subtract known gas percentages

Subtract the percentage of nitrogen (78%) and oxygen (21%) from 100%. So, $100 - 78 - 21=1$.

Answer:

1%
