Computing molecular weight (molecular mass) To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets. Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.
In low molecular weight gases such as helium, sound propagates faster as compared to heavier gases such as xenon. I gaser med låg molekylvikt, såsom
density of helium, gas is equal to 0.1785 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure.In Imperial or US customary measurement system, the density is equal to 0.01114 pound per cubic foot [lb/ft³], or 0.00010318 ounce per cubic inch [oz/inch³] .

Initially the rms… Most of them are below 22.42 l/mol, the ideal gas molar volume, but I noticed that hydrogen and helium do not. Hydrogen is 22.433 l/mol and helium is 22.434 l/mol. Why is this? What makes these particles, with mass, have higher molar volumes than the basically mass-less particles of an ideal gas?
