Question

How many atoms of neon gas are in 19.3 moles?

Answer 1

First, it doesn't matter what is counted in moles, whether it's atoms, molecules, ions, coins, chickens, etc.

`1mol = 6.02 * {10}^(23)`

So 19.3 moles of something(in this case neon atoms) is calculated like this:

`19.3 * 6.02 * {10}^(23) =`

`= 1.16186 * {10}^(25)`
