Three moles of helium gas (molar mass M = 4.00 g/mol) are in a rigid container that keeps the volume of the gas constant. Initially the rms speed of the gas atoms is 900 m/s.

In the ideal case of molecular exclusion, there is no attractive interaction C: Mass transfer Helium is the carrier gas commonly used with theese detectors.

Really, the RMS calculation gives you root mean square speed, not velocity. This is because velocity is a vector quantity that has magnitude and direction. At stp,4 grams of helium gas ( molar mass=4) occupies how much volume - 5537086 The graph below represents the velocity distribution of helium atoms at 800 K. The molar mass of helium gas is 0.004 kg/mole. The molar mass of nitrogen gas is 0.028 kg/mole. Helium is a chemical element; it is an inert gas or also known as noble gas. It is a colorless, odorless and tasteless gas. Helium gas is used to inflate balloons.

Helium is a chemical element; it is an inert gas or also known as noble gas. It is a colorless, odorless and tasteless gas. Helium gas is used to inflate balloons.

m = mass. M = molar mass (please note that m/M represents the number of moles - N). For each gas type from the drop down list, this ideal gas law calculator uses the molar masses from the periodic table of Mendeleev and requires three out of the 4 fields available (plus the gas where MM means the molar mass of the substance in question. Often, in these types of problems, you will be called upon to determine the molar mass of an unknown gas.
