Avogadro's Number - GED Science

Card 0 of 1

Question

How many molecules are in 3.72mol of fluorine?

Answer

Convert from moles to molecules using Avogadro's number:

$(\text{moles})\times(\frac{6.02\times10^{23}\text{molecules}}{\text{mole}})=\text{molecules}$

Use the moles given in the question to solve.

$3.72mol\times \frac{6.02\times10^{23}\ \text{molecules}}{1mol}=2.24\times10^{24}\ \text{molecules}$
