3. Nitrogen, when combined with oxygen, can form various oxides. 3.5 g of nitrogen gas is burned in oxygen to form 11.5 g of an
oxide of nitrogen. a) Determine the mass of oxygen burned. (Hint: The oxide contains ONLY nitrogen and oxygen!)
b)Using the data from the experiment, find the percent of nitrogen by mass in the oxide.
c) Using the data from the experiment, find the percent of oxygen by mass in the oxide.
