Yes it would

You would need to know the mass of the atom and Avogadro's number.

Avogadros number is the number of atoms that it would take to make the RMM of an atom the total mass in grams

Avogadros number is somethin like 6.023 * 10 ^ 24

So 1 atom of hydrorgen with a RAM of 1 would weigh 6.023 * 10 ^ -24 grams

Yes, but you would need to convert the number of atoms to moles and then convert moles to grams. One mole is equal to 6.02x10^23 atoms, so you would do 1 atom/6.02x10^23 atoms to find the number of moles in that atom. The result would be 1.66x10^-24 moles. Now you have to convert the number of moles to grams. You would use the molar mass of the atom of the element. The molar mass is the mass of one mole of an element, and it's in grams. You can find it on the periodic table (it's the average atomic mass). Since you didn't say what element that atom was, I can't calculate it for you, but you would do:
1.66x10^-24 moles x the molar mass of 1 mole of the element
and that would give you the mass of one atom of the element. I hope you've learned something about moles, or you probably don't have a clue what I'm talking about! :)

Certainly.

We know that a mole af atoms has 6.02 x10E23 atoms.

Take any element, e.g Carbon. A mole of Carbon-12 has 12.0 grams. Divide by Avogadro's number and you have grams per atom.
