Avogadro constant

Postby Savannah Torella 1L » Sun Nov 01, 2020 9:37 pm

When do you want to use the Avogadro constant? How are you able to tell when it is needed?

when converting to moles from number of atoms or vice versa, you would need to use Avogadro's constant.

Avogadro's number (6x10^23) represents the number of atoms/electrons/molecules in a mole of that substance. You'd want to use it to either convert atoms/electrons/molecules to moles or vice versa

Normally you'd want to use it when converting some other unit measurement into atoms/molecules or the other way around (1 mole of anything = 6.022 x 10^23). It's also included in some of the equations we use, but that just means you need to plug it in with the rest of your values. I think the main thing is understanding how it can convert a mole of an element/molecule into how many little parts there are in it.

We need to use this constant when we need to know the mass for one atom by dividing the molar mass from periodic table by this constant.

You use it when converting atoms to moles or moles to atoms.

Avogadro converts moles to "things" which is literally anything that isn't already defined: atomps, particles, ect

You use this constant to convert almost any quantified value (electrons, molecules, etc. ) into moles and vice versa by either dividing or multiplying by it.

When a problem asks for the number of photons, atoms, e.t.c you would use Avogadro's number

You can also find the mass of a single atom by dividing its molar mass with Avogadro's constant

It is important to use when converting moles to atoms or vice versa!

Avogadro's number is used when the question asks for the number of atoms, molecules, or formula units of a specific substance. It is a useful tool for these conversions.

Everyone else put it perfectly! Hope you understand now.

You use this constant to convert atoms/electrons/molecules into the number of moles, or conversely the number of moles into atoms/electrons/molecules.

You use it when converting between mass and mols of a substance. This substance can be an element or molecule.

The vast majority of the applications of the constant are in problems relating to stoichiometry. The units for the constant (which is used to find number of atoms, as represented by N*subscript A* on the constants and equations sheet) are inverse moles. Therefore it is used when converting between the number of moles and the number of atoms of a particular substance.

You would want to use Avogadro's constant when converting moles into atoms/electrons/particles. You would also conversely use when converting from atoms/electrons/particles to moles.
