Apr 26, 2006 · Using a periodic table, calculate the molar mass of chromium oxide (CrO2). The atomic weight of chromium is 52.00, and that of oxygen is 16.00. You must count the oxygen twice because there are two per formula unit of chromium oxide. 52.00 + 2(16.00) = 84.00 g/mol. Practice: Using a periodic table, calculate the molar mass of potassium sulfate ... ................
