A sealed vessel containing argon, oxygen, nitrogen has a total pressure of 1514 psi and particle pressure of 325 psi for oxygen and 649 psi for nitrogen. What is the partial pressure of argon in psi

The law of partial pressures states that each component exerting pressure contributes to the total, and the sum of these pressures equals the total exertion. This means that the pressure of all three gases added together equals 1514.

X + 325 + 649 = 1514

X=540

The partial pressure of Argon in this system is 540 pounds per square inch.
