nirtogen when combined w oxygen can form various oxides. 3.5 g of nitrogen Gas is burned in oxygen to form 1.5 G of an oxide of nitrogen. Determine the mass of the oxygen burned be using the data from the experiment find the percent of nitrogen by mass in the oxide see using those data from the experiment find the percent of oxygen by mass in the oxide D use the data from the experiment to find the empirical formula of the oxide of nitrogen E if you were given 100 mg sample of oxide how many milligrams of nitrogen would be in your sample
