Yes as is the molar mass of anything else.
Molar mass of NH3 = 17.03052g/mol
The molar mass of H2 = 2.0159 g/mol
Both the molar mass of magnesium (24.3g/mol) and the gas laws come into play in stoichiometry.
39.95 because that is the molar mass of Argon
There are more than one gas which has their molar mass of 28 g/mol. Nitrogen N2 and ethene C2H4 are two examples.
Molar mass of NH3 = 17.03052g/mol
Oxygen gas is composed of diatomic O2 molecules. From the Periodic Table, the atomic weight indicates that the molar mass of oxygen atoms is 16.0g/mole. The diatomic molecule O2 has twice the molar mass as oxygen atoms, and its molar mass is 32g/mole.
The speed of the molecules in a gas is proportional to the temperature and is inversely proportional to molar mass of the gas.
The molar mass of H2 = 2.0159 g/mol
The molar mass of any gas in liters is 22.4 For example The molar mass of O2 and O are both 22.4 since gas is compressible.
Both the molar mass of magnesium (24.3g/mol) and the gas laws come into play in stoichiometry.

There are more than one gas which has their molar mass of 28 g/mol. Nitrogen N2 and ethene C2H4 are two examples.
Molar mass of CO2 is 44. Molar mass of NH3 is 17
The rate of diffusion of a gas in inversely proportional to the square root of the molar mass. A small molecule (small molar mass) will diffuse faster than a large molecule (large molar mass). Not sure what the question is asking, but this should help.
16 grams or 32 grams, depending on what you're looking at.The mass of one mole of oxygen atoms is about 16 grams, but oxygen gas exists as a molecule (O2) so 1 mole of (O2) is 32 grams.
