calculate the total number of electron present in 3.2grams of oxygen gas |
|
Answer» 3.2 g oxygen molecules = 0.1 moles of oxygen molecules 0.1 moles O2 x avagadro's number = number of oxygen molecules since each oxygen molecule has 2 oxygen atoms, and each oxygen atom has 8 electons, each oxygen molecule has 16 electrons. multiply the number of molecules by 16...that will give you the total number of e- in 3.2 g O2. |
