Answer:
There are 0.499833942 moles of sodium in 3.01x10^23 atoms of sodium.
Explanation:
Given number of atoms= 3.01x10^23
We know,
1 mole of any element contains [tex]6.022*10^{23}[/tex] atoms of it.
According to this,
[tex]6.022*10^{23}[/tex] atoms of sodium= 1 mole of sodium
1 atom of sodium = [tex]\frac{1}{6.022*10^{23}}[/tex] moles of sodium
∴3.01x10^23 atoms of sodium= [tex]\frac{3.01*10^{23} }{6.022*10^{23}}[/tex] moles of sodium
=0.499833942 moles of sodium
So, there are 0.499833942 moles of sodium in 3.01x10^23 atoms of sodium.
