Calculating Formula Masses WORKSHEET Calculate the formula mass of each of the following substances. Use "whole number" atomic masses except in the cases of Mg and Cl. You must show your work for the complete process. Example Mg=24,3 grams/mole Cl = 35.5 grams/mole • The oxidation state for the two elements are Mg" and C. so the Chemical formula for this compound would be MgCl, • Combine the grams/mole for all of the atoms in the compound. 1 Mg atom x 24.3grams/mole = 24.3grams/mole for Magnesium 2 CI atoms x 35.5 grams/mole 71 gramsimole for Chlorine 19 Combine the grams/ mole for all of the atoms in the compound. 4. 149 24.3 grams/mole (1 Mg atom) +71 grams/mole (2 Cl atoms) 95.3 grams/mole for the compound MgCl, 7. Ca(NO₂) 2. NaF 5. (NH,) PO. 8. Mg(HCO) 3. CaCh 6. H₂SO, 9. Al, (HPO.), 10. Na.50, 10 H₂O (This is a hydrated compound; one that contains water of hydration. There are 10 water molecules for each 2 sodium and 1 sulfate. Calculate the mass as though it were written Na.SO, (H₂O).)
