Steps:
So for this we will be setting up a proportion. Since we know that for 20 L of air there is 0.78 L of CO₂, we can determine that for 1 L of air there is X L of CO₂ . We can set that up as such:
[tex]\frac{20}{0.78}=\frac{1}{x}[/tex]
From here we can solve for x. Firstly, cross-multiply:
[tex]20x=0.78[/tex]
Next, divide both sides by 20:
[tex]x=0.039[/tex]
Answer:
For 1 L of air, there is 0.039 L of CO₂
