How many moles are in 6.31x10^24 C atoms

Explanation:

1 mol of any chemical is 6.02 * 10^23

x mol of any chemical is 6.31 * 10^24

You should look at this before you put it in  your calculator. You should think roughly 10.

Now you can set it up as a proportion

1/x = 6.02 * 10^23/6.31 * 10^24        Cross multiply

6.02 * 10^23 x = 1 * 6.31 * 10^24      Divide by 6.02 * 10^23

x = 6.31 * 10^24 / 6.02 * 10^23

x = 10.48 mols.
