WebSo we're going to need 0.833 moles of molecular oxygen. And then I just multiply that times the molar mass of molecular oxygen. So, times 32.00 grams per mole of molecular oxygen. 0.833 times 32 is equal to that. If you go three significant figures, it's 26.7. 26.7 grams of oxygen, of molecular oxygen. WebCalculate the molar masses of the following chemicals: 1) Cl2 . 71 g/mol. 2) KOH . 56.1 g/mol. 3) BeCl2 . 80 g/mol. 4) FeCl3 . 162.3 g/mol. 5) BF3 . 67.8 g/mol. 6) CCl2F2 . 121 g/mol. 7) Mg(OH)2 . 58.3 g/mol. 8) UF6 . 352 g/mol. 9) SO2 . 64.1 g/mol. 10) H3PO4 . 98 g/mol. ...
