Next convert the grams to moles by dividing 293 grams by the atomic weight of sodium which is 2299 grams to get 1274. C40 H667 O533 of the compound. Video for How To Solve Empirical Formula Solving For Empirical Formulas - YouTube.
To determine an empirical formula using weight percentages start by converting the percentage to grams.
Change of each element into grams for example if the compound contains 40 carbon then change it to 40 g carbon Convert grams of each element into moles by dividing grams by molar mass. The empirical formula is thus N 2 O. Empirical formulas can be determined from the percent composition of a compound as discussed in section 68. How to Find the Solution.
