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?

Explanation

To solve the problem of finding the partial pressures of nitrogen (N₂), oxygen (O₂), and argon (Ar) in dry air at sea level, we can follow these steps:

### Step 1: Determine the total mass of dry air
Assume a total mass of dry air to be 100 grams for easier calculations. This assumption allows us to directly use the percentage composition by mass.

### Step 2: Calculate the mass of each component
Using the composition percentages:
- Mass of N₂ = 75.5% of 100 g = 75.5 g
