If a gaseous mixture is made by combining 1.55 g ar and 1.80 g kr in an evacuated 2.50 l container at 25.0 ∘ c, what are the partial pressures of each gas, p ar and p kr , and what is the total pressure, p total , exerted by the gaseous mixture

Partial Pressure Ar = 0.379 atm

Partial Pressure Kr = 0.210 atm

P total = 0.589 atm

Explanation:

First let's convert the masses of both gases to moles, using their respective atomic weight:

Now we can calculate the partial pressure of each gas, using PV = nRT:

P = 0.379 atm

P = 0.210 atm

Finally, the total pressure is the sum of the partial pressure of each gas:

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
