Thread: unit conversion

Hi I'm trying to get help for this problem. Converting millimoles to milligrams. I'm having such difficulty in trying to find a conversion unit to use. Thanks for any of your help.

I think it depends of millimols of what. A mole of carbon has a different weight than a mole of gold. Think a mole as a quantity of atoms. A mole of carbon has a same quantity of atoms as a mole of gold, but gold atoms are very much heaviest than the carbon's one. So it really depends.
