Question

Calculate the number of moles of atoms in 3.01×1024 of magnesium chloride, .

Answer 1

Each mole of any molecule contains 6.022 * 10^23 of that molecule...

Answer 2

Use avogadro's number. Use dimensional analysis to cross cancel units just as you did in your algebra class, to find whatever it is you are looking for..

Avogadro's number: \[6.022 \times 10^{23} \frac{ mol }{ atoms }\]
