If i have 13 g of c, how many moles of c do i have?

C = Carbon

If you look in a periodic table and see the mass number for carbon. Its estimated around 12.

I believe it's between 1-2 moles.

All you have to do is 13/12 which will give yoy the estimated answer which is around 1.08 mole.

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this
