Answer:
[tex]7.53*10^{23}[/tex] atoms NaOH
Explanation:
To figure this out, we need to use Avogadro's number, which is [tex]6.022*10^{23}[/tex] . 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:
[tex]1.25 mol * \frac{6.022*10^{23} atoms}{1 mol} =7.53*10^{23}atoms[/tex]
Thus, the answer is [tex]7.53*10^{23}[/tex] atoms NaOH.
Hope this helps!
