Agas made up of atoms escapes through a pinhole 0.155 times as fast as h2 gas. write the chemical formula of the gas.

he ratio of the RMS velocities is 0.837 Now the RMS velocity is inversely proportional to the square root of the Mol Wt So we have V1/V(N2) = sq rt (28/M1) So [V1/V(N2)]^2 = 0.837^2 = 0.70 = 28/M1 from which M1 = 28/0.7 = 39.97 (Ar)

It conforms what ever surface its in.

answer: mole of the gas

answer: mole of the gasexplanation:

answer: mole of the gasexplanation: this is because 1 mole of a gas is 22.4dm³, which is use in ideal gas
