Editable handout | Word, Size 0. The mole is a conversion factor to convert from amus to grams. So, in the same way, 1 mole of carbon is 12 grams because it is 12 atomic mass units on the periodic table and 1 mole of iron is 56 grams because it is 56 atomic mass units on the periodic table. What is the relationship between mole and amu? 02x10^23 so that when it was multiplied by the amu it would give a nice number like 1g (shown above). The energy released from the fission of one atom of thorium-232 is 191. Thus we must consider the makeup of an H2 molecule, where we see that it is a diatomic molecule. Actually, it is both of those things, but, in a chemistry context, a mole is just saying you have this much of something. All right, so we started off with 15.
Generally when working with Avogadro's number and the mass of a proton or neutron, you wouldn't substitute the values in.
Nuclear power has the potential to supply large amounts of energy from a relatively small amount of starting material (when compared to combustion of fossil fuels). Now, what does that mean? Nuclear fuels have different yields of energy per unit mass (as well as radioactive wastes).
Let's say that someone were to walk up to you and say, hey, you, I have a 15. About This Quiz & Worksheet. Using moles to convert between measures of mass and the number of atoms in a sample.

Pause this video and try to think about that. If I say I've got a dozen of eggs, how many eggs do I have?
