a) Write the formula for nitric acid. b) Without doing a calculation, estimate which element in nitric acid occurs with the greatest mass percentage.
How am I supposed to complete part b without doing a calculation?

Well mass percentage is calculated by the mass of the component over the total mass of the mixture. So if you just think about Nitric Acid you know there is 3 times the number of oxygens to one nitric acid. The higher the mass of the component then the higher its mass percentage will be, so oxygen is seemingly going to have a greater mass percentage than nitrogen or hydrogen.
