1.68 moles of NaCl (table salt) contains how many molecules?

Feb 7, 2016

$1.01 \times {10}^{24} \text{ molecules}$.

Explanation:

To calculate the number of molecules in a given number of mole, we can simply multiply by Avogadro's number which is equal to $6.022 \times {10}^{23}$.

Therefore,

? "molecules"=1.68 cancel(mol)xx(6.022xx10^(23)"molecules")/(1cancel(mol))= 1.01xx10^(24) " molecules".

I hope you find this helpful.
