At sea level, the composition of dry air...

At sea level, the composition of dry air is approximately `N_(2)=75.5%`, `O_(2)=23.2%`, and `Ar=1.3%` by mass. If the total pressure at sea level is `1 "bar"`, what is the partial pressure of each component?

To find the partial pressure of each component of dry air at sea level, we can follow these steps: ### Step 1: Assume the Mass of Dry Air Let's assume the mass of dry air is 100 grams. This simplifies our calculations since we can directly use the percentages by mass to find the mass of each component. - Mass of Nitrogen (N₂) = 75.5 grams - Mass of Oxygen (O₂) = 23.2 grams - Mass of Argon (Ar) = 1.3 grams ...
