JoyfulSilhouette speaks the truth! <br />
I miss chemistry.
i tried to add u but it wouldn't let me view ur profile...maybe u can add me :-)
It's not working for me either for whatever reason o.O
Number of grams = (# of moles) × (molar mass)
if that wasn't clear enough... divide total number of grams by the molar mass of the compound and you will get moles...don't forget your significant digits
Oh man, going crazy with the algebra action up in here!!
each element has a relative atomic or molecular mass (RMM or RAM). (refer to periodic table).<br />
No. of Moles = mass/(RAM or RMM)<br />
Balance out the chemical equation first, and then you can convert.
Used to know- way, way back. But if it helps you, mole is a specific number of atoms, or particles, of which each has specific atomic mass.
