Moles to Molecules

Remember Avogardo's number?

6.02 x 10^23

Well in this lesson we learned about how to convert Moles into Molecules

We did examples like:
-How many atoms are there in 1.5 mol of Iron?

We start off like this

1.5mol x __________

Since we have to cancel out moles, to cross multiply out the mols, you have to put 1 mol (usually) on the bottom

1.5mol x __________
                  1 mol

And remember Avogardo's number? Well plug it in the top!

1.5mol x 6.02 x 10^23 molecules
                         1 mol

So since the moles cancel out, we multiply 1.5 mol and Avogardo's number and we get....

1.5mol x 6.02 x 10^23 molecules = 9.0 x 10^23

                         1 mol

Well thats all for today guys!
