Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Please help me learn how to think regarding 75. I have it balanced and I have the formulas. Pressure and Temp constant. O2 and H2O not gaseous. I tried assuming STP and converting to moles. ( all are .89) . Oxygen is in excess thus ch4 and NH3 are limiting and .89 moles. They would create .89 moles of HCN since ratios are equal and plugging thise numbers back into my STp assimption gives me 19. Answer is 13. my approach of assumption looks wrong. So I tried V 1 / N 1 = v2 / N 2 thus N2 /N1= V2 / V 1 No dice then i thought 4 volumes in balanced equation produce 2 volumes hcn so 40 would produce 10 Close but not 13 pkease help me think right
