      • Multiply the atomic weight of each element in the compound by the quantity of atoms of that element in the compound's formula, then add all the resulting products. In the case of water, multiply the atomic weight of hydrogen by two, and the atomic weight of oxygen by one, then add the products.

    Converting between the mass of a substance and the number of moles. You need to practise this until you can do it without really thinking about it. The formula is this: So, if 1 mole of a substance weighs 40 g and you have 10 g of it, you have 10/40 moles - in other words you have 0.25 moles.

    Calculate the answer. 0.0114 gHg × 1 mol Hg 200.59g Hg = 5.68 × 10 − 5 mol Hg. Think about your result. Since there are 200.59 g Hg in 1 mol Hg, 0.0114 g Hg must be a very small fraction of a mole. The answer is rounded to three significant figures since the fewest significant figures in the calculation is three.
