Determine how many moles of Gold atoms you have. Steps 1: Obviously, you are solving for moles. Step 2: Looking at the periodic table, you find that gold weighs 197 AMU, or 197 grams per mole. Your conversion factor is then 1 mole=197 grams. Step 3: We know (or we are given) the weight of the chain, in grams. Write this over 1: 400 g

In order to find out how many atoms there are in something when you have the mass, you have to first convert it to moles. The same goes for converting from atoms to grams, you have to convert to moles first. This is why chemists say that moles are central to chemistry; so much of what they do at some point requires them to find the moles.
