WebApr 3, 2024 · The atomic weight of iron = 56 grams One gram atomic weight of iron is equal to one mole of iron atoms. Therefore, 56 grams of iron =$6.023\times {{10}^{23}}$ atoms of iron. Hence, 560 grams of iron =$6.023\times {{10}^{24}}$ atoms of iron = 10 times the Avogadro’s number of atoms. Now, the molecular weight of nitrogen = 28 grams, WebSolution – Atomic mass of iron = 55.9 g Mass of the 1 mole of iron = 55.9 g Or, by using formula, mass = atomic mass x number of moles Mass of the 0.5 mole of iron = 55.9 x 0.5 g = 27.95 g Now, Check your understanding – 1.
