because they really wanted too
The mole fraction of gases is not always equal to unity. The mole fraction of a gas in a mixture is equal to the number of moles of that gas divided by the total number of moles of all gases in the mixture. It is a dimensionless quantity that ranges from 0 to 1.
No. A liter is a volume measurement for fluids (liquids and gases). A mole is 6.022 x 1023 of anything. In gases at STP, 22.4L = 1mole.
For Ideal gases, mole fraction=volume fraction
Diffusion.
Gases are useful for lots of things. you might need to specify on what gas it is?
At STP (standard temperature and pressure), all gases have the same volume of 22.4 liters per mole regardless of their identity. Therefore, 1.00 mole of each gas would occupy the same volume of 22.4 liters.
Gases are compressible.
so that you are able to breath
No, mole percent and volume percent are not necessarily equal for a gas. Mole percent is the ratio of the moles of a gas to the total moles of all gases in a mixture, while volume percent is the ratio of the volume of a gas to the total volume of all gases in a mixture. The two can be equal only if the gases have the same molar volume at the given conditions.
Since the volume ratio of two gases in a chemical reaction is directly proportional to the mole ratio of the reactants, you can infer that the mole ratio of lead nitrate to sodium iodide in their reaction is the same as the volume ratio of the gases involved. This allows you to determine the stoichiometry of the reaction.
It is the number of particles in one mole of a given substance. used to convert units.
Avogadro discovered the concept of the mole by proposing that equal volumes of gases at the same temperature and pressure contain the same number of particles. This idea laid the foundation for the concept of the mole as a unit of measurement for the amount of substance.
