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

`3.91x10^(24)molecules`

Step-by-step 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`
