Example: You are massing a 24 K gold chain, and find that it weighs 400 grams. 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.
