how many molecules are in a mole of molecules?
22224
One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro's number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole).

The number of carbon atoms present in 1 g of CH4O are to be stated. Concept Introduction: A mole of a substance is defined as the presence of exactly 6.02214076×1023 atoms/molecules.

Answer: 1 mole of anything contains 6.02 x 1023 particles. (Note that "mol" is the abbreviation for mole.) So, 4.21 mol of hydrogen gas contains 4.21 x 6.02 x 1023 = 2.53 x 1024 molecules of hydrogen.

A mole of a substance or a mole of particles is defined as exactly 6.02214076×1023 particles, which may be atoms, molecules, ions, or electrons.

In order to have one mole of things, let's say particles, you need to have 6.022⋅1023 particles → this is known as Avogadro's constant and acts as the definition of the mole. So, in one mole of nitrogen gas you have 6.022⋅1023 molecules of nitrogen gas, N2 .

If I have 6.022×1023 H2 molecules, I have a mass of 2 gram of hydrogen molecules. If I have 6.022×1023 C atoms, I have (approximately!) 12 grams. The mole is thus the link between the micro world of atoms and molecules, and the macro world of grams and litres, the which we can easily measure by mass or volume.

A mole is 6.02⋅1023 (avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses.

A mole is just a unit of measurement. Avogadro's number is equal to 6.022⋅1023 molecules/mole.

For phosphorous or any chemical compound, a mole contains 6.022⋅1023 molecules in it. So if you have 1.20⋅1025 (that's what I assume you meant) atoms of phosphorous, then just divide by Avogadro's number to find the number of moles.

A pound-mole is comprised of 6.022 141 79 × 1023 453.59237 molecules, i.e. the pound-mole is that amount of substance that contains the same number of elementary entities as there are atoms in 453.59237 grams of carbon 12.

one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

Explanation: I mole or bromine refers to 6×10^23 molecules of bromine. But 1 molecule of bromine has 2 atoms.

There are 6,022*10^23 molecules in a mole, and there are 3 phospates in one ATP molecule and 2 of them may be splitted off. 2 * 6,64 * 10^(-20) = 1,33 * 10^(-19) joules.

So, from this we know there are 6.023 × 10^23 molecules in one mole of CH4. To find how many molecules are present in 5.8 moles of CH4, all we have to do it multiply Avogadro's number by 5.8! Therefore, there are 3.5 x 10^24 molecules in 5.8 moles of CH4.

Use Avogadro's number to convert moles into molecules: 0.0211915 mol × 6.02×1023 molecules/mol = 1.28 × 1022 molecules.

The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

1.204x1024 molecules = 2.00 moles. 1.5x1020 molecules = 2.5x10-4 moles. 3.4x1026 molecules = 560 or 5.6x102 moles.
