Answer:

In one mole of freon gas there are 2 moles of fluorine, and 2 moles of chlorine, and 1 mole of carbon atoms.......

Explanation:

And thus the atomic ratio #C:Cl:F=1:2:2#.

Here, we used the mole as our unit, #1# #"mole"# #-=# #6.022xx10^23*mol^-1#. I could have equally used dozens, or tens, or 100's, as our unit of measure. It is just that #1# #"mole"# of #""^12C# atoms has a mass of #12.00*g# precisely, and thus we can make the link between atoms and molecules, which we can't see, with the macro world of grams, and litres, whose quantities we can weigh out on a balance, or in a flask.

Can you calculate the mass of a mole of #"freon"# in grams?
