Question

Describe how you mathematically convert the number of molecules of a

substance to moles? Create an example. PLEASE HELP.

Answer 1

e.g converting 6.55×10^24 molecules of Sodium to moles.

We use Avogadro's number NA= 6.02×10^23 molecules.

Step-by-step explanation:

`6.02 * {10 }^(23) molecules \: are \: in \: 1 \: mole \: of \: sodium \\ 6.55 * {10}^(24) molecules \: will \: be \: in \: ( \frac{6.55 * {10}^(24) * 1}{6.02 * {10}^(23) } ) \\ = 10.88 \: moles \: of \: sodium`
