Question

In one mole of freon (`C Cl_2F_2`), what is the chemical ratio of carbon to chlorine to fluorine?

Answer 1

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?
