neon diffuses 1.4 times as fast as argon.
Neon diffuses 1.4 times as fast as argon.
The molar mass of Ar = 39.948 g/mol
40 g
The molar mass of Argon is 39.95g. Therefore 1 mole of Argon is 39.95g
39.95 because that is the molar mass of Argon
The ideal gas equation.Pressure * volume = moles * the R constant applicable * temperature in KelvinPV = nRT(1 atmosphere)(202 L) = n(0.08206 L*atm/mol*K)(298.15 K)= 8.256 moles argon gas---------------------------------now, a little stoichiometry though you will see that you have the answer here8.256 moles Ar (6.022 X 1023/1 mole Ar)(1 moles Ar atoms/6.022 X 1023)= 8.26 moles argon atoms==================

Diffusion
39.95 because that is the molar mass of Argon
39.95 because that is the molar mass of Argon
The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move - the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
Cl2 has a molar mass of about 71 g/moleArgon has molar mass of about 40 g/mole Thus, Argon will diffuse faster than Cl2 gas, or put another way, Cl2 will diffuse slower than argon.
