Web22 de dic. de 2024 · To determine an empirical formula using weight percentages, start by converting the percentage to grams. For example, if your empirical formula contains 29.3 percent sodium, convert it to 29.3 grams. Next, convert the grams to moles by dividing 29.3 grams by the atomic weight of sodium, which is 22.99 grams, to get 1.274. WebSo to figure out the empirical formula for ethene, we have to find the smallest whole-number ratio that describes the relative number of different atoms. So we divide both the two and the four by two, to get the empirical formula CH2. If we want to get the molecular formula from the empirica.
