695 moles 1 gram 3.45 mole

1 mole

I actually got a different answer this time, because I did the work differently. Basically I don't know how to do this sort of problem, so I just need a basic rundown on how to do it. Thanks for your help.

**bobpursley**, Tuesday, June 2, 2009 at 6:52pmOK, your totals for the atoms are 55.85+3*35.45=162.2 grams per mole.

You have 3.45 moles, so you multiply the grams/mole by that. It is 559grams.

Practice this here for a few minutes.

Do it for FeCl2, and C6H12O6
