The formula for dinitrogen monoxide is N₂O. If a sample of the oxide was found to contain 0.0800 g of oxygen, how many grams of nitrogen would it contain? A)0.140 B)0.280 C)0.560 D)0.0700

Question

Quizplus · Accepted Answer

The formula for dinitrogen monoxide is N2O, which means that for every 2 moles of nitrogen, there is 1 mole of oxygen. The molar mass of oxygen is 16.00 g/mol, so 0.0800 g of oxygen is equal to 0.0800 g / 16.00 g/mol = 0.005 mol of oxygen. Since there is 1 mole of oxygen for every 2 moles of nitrogen, there must be 2 * 0.005 mol = 0.010 mol of nitrogen in the sample. The molar mass of nitrogen is 14.01 g/mol, so 0.010 mol of nitrogen is equal to 0.010 mol * 14.01 g/mol = 0.140 g of nitrogen.
