An atom's actual mass is 0.00000000000000000000000167 grams. You can see why scientists needed a better system! 😅 That's why chemists invented the concept of relative atomic mass comparing every atom's mass to a fixed reference point (carbon-12) instead of using impossibly tiny numbers. It's like measuring height in centimetres instead of nanometres: same information, much easier to work with. Today you'll master Relative Atomic Mass including how to calculate it for elements with multiple isotopes. Get your calculating mind ready! 🧮⚗️📐
