Can someone explain Avogrado's #?

Postby noelle_lipschutz_3F » Sun Oct 25, 2020 3:38 pm

Avogrado's Constant is 6.02214x10^23 mol-1

Avogadro's number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10^23. The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any).

How can this constant represent multiple units? I am still puzzled by this

Because, Avogadro's number represents the number of atoms, ions, or molecules in one mole of a substance. Basically, one mole of a substance is equal to 6.02214x10^23 units of that substance. The units can be measured in either atoms, ions, or molecules - this would be decided based on what the question is specifically asking for.
This constant is used to convert between moles and numbers of particles, and atoms, ions and molecules are all particles.

Avogadro's number is just the amount of OBJECTS in a mole of x. So if I were to say that there is 1 mol of carrots in Billy's garden, then there'd be 6.0221*10^23 carrots in his garden. Hope this helps!

Avogadro's number is the number of objects in one mole of a substance. You can use it to describe the number of atoms, molecules, etc there are in a mole of whatever substance because it is just a number.

Avogadro's number is just the number of "something" (units) in a mole. A "dozen" is 12 of "something" -- that could be 12 pounds, 12 kilograms, 12 grams etc. Think of the mole in the same way regarding avogadro's number. A mole is [avogadro's number] of an object.

Avogadro's number is just a set number of anything, and we then assign to units to it based on what we're looking at. Essentially it's like the number 10 or 5, and we assign units to this number to represent what it is (i.e. molecules of water, eggs, test questions, etc.)

To think of its simply, one mole of a something is equal to 6.02x10^23 units of that specific thing. It could be cars, bananas, footballs, etc, It really does not matter. A mole of something is basically the avagadro's number of that thing and that's why it can be universally used for any atom or substance.

Avogadro's constant is the number of something in a mole. It can be the number of atoms in something, molecules in something, it is just a number without units.

I don't actually know what it is at all but thanks for asking this because I can look through the replies for the answer now!
