Question

3. The percent by mass composition of a salt was found to be 56.58% potassium, 8.68% carbon, an 34.73% oxygen. What is the empirical formula of this salt?

Answer 1

to your element above by respective Solution, found to be The Percent by mass Composition of a Salt was 58.58% Potassium, 8.68% Conbon and 34.74% oxygen. Convent into moles of each element - Divide the masses obtained above by respect a tomic masses of various elements. This gives the number of moles of constituent elements in the Compound- Moles of Potassium = 58.58 = 1.45 Moles of Conbon = 8.68 20.723 Moles of chlorine = 34.74 2.172 11 Divide each of the mole value obtained above by the smallest number amongst them. Since 0.723 is smallest value. division by it gives a nation 1.45 0.723 2.172 Kicio 0.723 0.723 0.723 © 2:1:3 write down the empirical formula by mentioning the numbers after writting the symbols of respective elements sols of go2 Kq CO₂ (potassium Carbonate) is, thes, the Tobri empirical formula of the above comen
