Air is 20.9% oxygen by volume.How many mL of air contains 175 mL of oxygen?
So lets say we have 100 mL of air then this will contain 20.9 mL oxygen.
Thus 100 mL/20.9 of air will contain
1 mL of oxygen.
So how many mL of air contain 150 mL of oxygen?
To determine the volume of air that contains 175 mL of oxygen, we need to consider that air is roughly 20.9% oxygen by volume.
First, let's calculate the total volume of air needed to contain 175 mL of oxygen. We can use the formula:
Total volume of air = Volume of oxygen / Percentage of oxygen in air
Substituting the given values:
Total volume of air = 175 mL / 0.209
Now, you can proceed with the calculation:
Total volume of air = 837.32 mL (rounded to two decimal places)
Therefore, 837.32 mL of air would contain 175 mL of oxygen.
