: Cancel the label, then punch the numbers in on your calculator. 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.

Sep 17, 2015 · Estimate how many atoms are in the bottle. Your group must reach consensus. Read This! A long time ago chemists discovered what you have just discovered: The relative masses of the elements can be used to “count” atoms. If you measure out a sample equal to an atom’s atomic mass in grams, you always end up with the same number of atoms.

Modern isotopic counting techniques (accelerator mass spectrometer) can date things as old as 70,000 years. This is done by counting individual C-14 atoms (the parents) remaining in the once living organisms. A very accurate age can be determined. The daughter atoms (Nitrogen-14) are lost to the atmosphere as elemental nitrogen. Procedure:
