Answer:
e.g converting 6.55×10^24 molecules of Sodium to moles.
We use Avogadro's number NA= 6.02×10^23 molecules.
Explanation:
[tex]6.02 \times {10 }^{23} molecules \: are \: in \: 1 \: mole \: of \: sodium \\ 6.55 \times {10}^{24} molecules \: will \: be \: in \: ( \frac{6.55 \times {10}^{24} \times 1}{6.02 \times {10}^{23} } ) \\ = 10.88 \: moles \: of \: sodium[/tex]
