my teacher gave me a project with radium and just asked for one mole=___ grams.

However many amu's a single atom weighs, that's how many grams 1 mol of that element will weigh. So since a Ra atom is 226 amu, 1mol of Ra will weigh 226g.

1 mole is 6.0225 x 10^23 units of anything.
Examples:
1 mole of radium has 6.022 x 10^23 atoms of radium
1 mole of water has 6.022 x 10^23 molecules of H2O
1 mole of humans is 6.022 x 10^23 people (more than all the people that have ever lived since the beginning of time)
The question how many moles are in radium depends on how much radium you are talking about.

I concur with John N. You need a specific measurement of radium to determine how many moles are in that sample.

to help you start....
1 mole of anything = 6.02 x 10^23
