Avogadro constant - Wikipedia, the free encyclopedia
Mole (unit) - Wikipedia, the free encyclopedia Avogadro's Number is the number of molecules in a mole. One mole of a compound has a mass of <amu> grams. (eg. 1 mole of carbon-12 has a mass of 12 grams) What you need to do is determine the mass of the specified molecule. Then determine how many moles that is. Next step is to determine the number of Zn ions in that. (be careful of the possible "gotta" in the molecular formula) |
