How can a mole of any substance contain the same number of particles?

That's just the way it was set up. 6.022x1023 atoms of an element equals one mole of that element. 6.022x1023 molecules of a compound equals one mole of that compound. Remember, a mole does not measure weight. One mole of hydrogen weighs a lot less than a mole of acetic acid. A mole just means 6.022x1023 particles, whether those particles are atoms, ions, molecules, or ionic compounds.

Is 1 mole of particles a very large number of particles or a very small number?
1 mole of representative particles of a substance is a very large number. It represents 6.02294x1023 particles.
Any substance that contains Avogadro's number of particles is called a?
A mole is the unit of measurement based on Avogadro's number. It measures the number of atoms or molecules in a substance.
How is a mole used to indirectly count the number of particles of matter?
A mole contain 6,022 140 857.10e23 atoms or molecules or ions.
What is the name given to the number of particles in a mole?
The name given to the number of particles in a mole is Avagadro's number/constant
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.
What does an Avogadro's number of a substance is called a mole mean?
It is the number of particles in a mole of any substance
What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
Avogadros number is the number what?
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
What is used to measure the number of representative particles in the substance?
mole
Is 1 mole of particles a very large number of particles or a very small number?
1 mole of representative particles of a substance is a very large number. It represents 6.02294x1023 particles.
Does 1.0 mole of carbon contain Avogadro's number of particles?
Yes. 1 mole of all elements (including carbon) or compounds contain Avogadro number of particles (6.023 x 1023 particles)
How many particles are there in one mole of a substance?
There may be about 6.022 x 1023 atoms in one mole, but we must ask this question: a mole of what? While a mole of a substance contains about 6.022 x 1023 particles of that substance, the substance may not be composed of single atoms. As this is a critical issue for the budding chemist, let's investigate just a bit.A mole of any substance contains Avagadro's number of "basic units" of that substance. Avagadro's number (or the Avagadro constant) is about 6.022 x 1023 "basic units" of a given substance. In the case of helium, we'll have that many atoms of helium. That's because if we encounter helium floating around in air, it is found in units of single atoms. In the case of hydrogen or oxygen, these gases exist as diatomic molecules. That means there are two atoms in a given molecule of each gas, and there will be 2 times 6.022 x 1023 atoms in a mole of hydrogen or oxygen.Going further, we'll see about 6.022 x 1023 molecules of H2O in a mole of water. Using the logic above, we'll have about 6.022 x 1023 atoms of oxygen in a mole of water, and twice that many atoms of hydrogen in the mole of water.It is critical to the understanding of the chemist to be clear about the mole and what it represents.
What is Avogadro's Number used for?
It is the number of particles in one mole of a given substance. used to convert units.
Why do we find it useful to have two units of the amount of substance the kilogram and mole?
When we are concerned with the number of particles than we use Mole as the unit of amount of substance because one mole of a substance contains the equal number of particles (i.e., 6.022×10^-23)Butin case when we are concerned quantity of matter we use the unit Kilogram.
Avogadro's is useful for what?
It is the number of particles in one mole of a given substance. used to convert units.
Which of these is known as Avogadro's number?
It is the no.of particles in 1 mole of that Substance.
Any substance that contains Avogadro's number of particles is called a?
A mole is the unit of measurement based on Avogadro's number. It measures the number of atoms or molecules in a substance.
