A certain laser uses a gas mixture consisting of 9.0 grams of Hydrogen chloride, 2.0 grams Hydrogen gas, and 165.0 grams of Neon. What pressure is exerted by the mixture in a 75.0 liter tank at 22 degree Celsius? Which gas has the smallest partial pressure?

  1. The long way is to use PV = nRT and solve for pressure of each gas. n = grams/molar mass or atomic mass when dealing with grams.
    Then add the partial pressures to find the total pressure.
