One mole represents the same number of particles, regardless of the substance. Since the volume that a mole occupies is determined by the substance's molar mass and density, one mole of any substance at the same conditions of temperature and pressure will have the same volume.
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.
Molar volume of gas is the volume which one mole of the gas occupies. According to Avogradro's law, ALL GAS HAVE THE SAME VOLUME AT THE SAME PRESSURE AND TEMPERATURE. So one mole of all gases occupies 22.4dm3 at s.t.p (273K 760mmHg) - i.e 22.4dm3 is the molar volume of all gases at s.t.p. (you can convert to other conditions of temperature and pressure using Boyle's, Charles' or General gas equations)
Avogadro's number is the number of "elementary entities" (usually atoms or molecules) in one mole. It is 6.0221415 × 1023
One or three moles of anything is just different Q U A N T I T I E S of M A T T E R .Concentration is just something else than moles (quantity is not the same as concentration): it can be calculated as moles P E R volume
The volume occupied by 2.12 moles of nitrous oxide is 9.35. A mole is described in chemistry as an amount of pure substance containing the same number of chemical units as there are atoms.
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.
If two samples of elements each represent one mole, then they will contain the same number of atoms. This is because one mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, both samples will have the same number of atoms, even if they are different elements.
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 occupies 22.4 L
yes they should live in the same state they represent
It occupies 22.4 L
The right question should be: Does one mole of iron weigh the same as one mole of iron oxide? The answer is NO, Iron Oxide weighs more.
PV=nRT 32 gram O2 = 1 mole O2 (1atm)(V) = (1 mole)(.0821)(273) V = 22.4 L
It occupies 22.4 L
