Question

How many chlorine molecules are in 6.5 moles of chlorine

Answer 1

6,02·10²³ --- 1 mol
X -------------- 6,5 mol
X = 6,02·10²³×6,5
X = 39,13·10²³ molecules of Cl₂

Answer 2

Answer:

$3.91x10^{24}molecules$

Explanation:

A chlorine molecule is composed of two chlorine atoms. $Cl_{2}$

One mol is equal to $6.02x10^{23}$ molecules.

So we have to calculate:

 $1 mol Cl_{2} = 6.02x10^{23} molecules$

 $6.5 mol Cl_{2}= x$

$\frac {6.5molesX 6.02x10^{23}}{1}=x$

$x=3.91x10^{24}molecules$
