Answer:
[tex]3.91x10^{24}molecules[/tex]
Explanation:
A chlorine molecule is composed of two chlorine atoms. [tex]Cl_{2}[/tex]
One mol is equal to [tex]6.02x10^{23}[/tex] molecules.
So we have to calculate:
[tex]1 mol Cl_{2} = 6.02x10^{23} molecules [/tex]
[tex]6.5 mol Cl_{2}= x [/tex]
[tex]\frac {6.5molesX 6.02x10^{23}}{1}=x[/tex]
[tex]x=3.91x10^{24}molecules[/tex]
