Ptotal = PHe + PH2 + PAr
Substitute and solve for the only unknown.
CAUTION: You MUST have the pressures in the same unit. They are in different units in the problem.
A closed container with a mixture of hydrogen, helium, and argon has a total pressure of 3.00 atm. The partial pressure of hydrogen is 0.550 atm and the partial pressure of argon is 615 mm Hg. What is the partial pressure of helium?
