Question

11. Determine the number of atoms in 1.25
mol of NaOH.​

Answer 1

`7.53*10^(23)` atoms NaOH

Step-by-step explanation:

To figure this out, we need to use Avogadro's number, which is
`6.022*10^(23)` . This number denotes the number of atoms in 1 mole of any substance.

Right now, we have 1.25 moles of NaOH. So, let's set up an equation:

`1.25 mol * (6.022*10^(23) atoms)/(1 mol) =7.53*10^(23)atoms`

Thus, the answer is
`7.53*10^(23)` atoms NaOH.

Hope this helps!
