Problem: The drawing below represents a mixture of three different gases.If the total pressure of the mixture is 1.55 atm, calculate the partial pressure of the red gas.

Recall that the partial pressure of a gas (P_Gas) in a mixture is given by:

$P_{Gas} = X_{G a s} P_{Total}$

where χ_Gas = mole fraction of the gas and P_total = total pressure of the gas mixture.

The mole fraction of the gas is then given by:

$m o l e f r a c t i o n (X) = \frac{m o l e o f gas}{total mass}$

The drawing below represents a mixture of three different gases.

A diagram shows a mixture containing five blue, two red, and three yellow gas molecules.

If the total pressure of the mixture is 1.55 atm, calculate the partial pressure of the red gas.
