Fill in the blanks:
Because the ___________ opf cobalt is ______, we know that 1 mole of cobalt weighs _____ grams, so therefore we know that 117.86 grams is equal to _____ moles of cobalt. A mole is a measure of the number of atoms, so we want to find how heavy ______ moles of gold is. This is simple, because we know that the ___________ of gold is _____, and so we know that _______ moles of gold must weigh _______ grams, this amount of gold has the same number of atoms as 117.86g of Colbalt.
Wasn't that easy?
