In this case, a blue gas molecule or a red gas molecule in a mixture of gases. In this case, two types of gas molecules, red and blue. So another way of representing this formula or equation is the following. So we can represent the partial pressure of any gas in a mixture of gasses by the following equation. The partial pressure is equal to the mole fraction of that gas in our mixture times the total pressure. In other words, I want to represent this in this following way let's see what we do.
