To get the amount of amus in Fe2O3 which is iron III oxide, we simply multiply the amus of iron by 2 (56 x 2 = 112) and the amus of oxygen by 3 (16 x 3 = 48) and add them to get 160amus. This is because there are two iron atoms and three oxygen atoms in the iron III oxide molecule. Hope that helps! When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.”.
