To determine the empirical formula of the compound, we need to convert the percentages into moles.1. Assume we have a 100 g sample of the compound. This means we have:- 28.6 g of sodium  Na - 46.8 g of sulfur  S - 24.6 g of oxygen  O 2. Convert the mass of each element into moles by dividing by their respective molar masses:- Moles of Na = 28.6 g /  22.99 g/mol   1.243 mol- Moles of S = 46.8 g /  32.07 g/mol   1.459 mol- Moles of O = 24.6 g /  16.00 g/mol   1.538 mol3. Divide each mole value by the smallest mole value to get the mole ratio:- Na: 1.243 / 1.243  1- S: 1.459 / 1.243  1.17- O: 1.538 / 1.243  1.244. Round the mole ratios to the nearest whole number:- Na: 1- S: 1- O: 15. Write the empirical formula using the whole number mole ratios:The empirical formula is NaSO.
