50 ml. of a mixture of NH3 and H₂ was completely decomposed by sparking into nitrogen and hydrogen. 40 ml of oxygen was then added and the mixture was sparked again. After cooling to the room temperature the mixture was shaken with alkaline pyrogallol and a contraction of 6 ml. was observed. Calculate the % of NH3 in the original mixture. (Assuming that nitrogen does not react with oxygen.) (A) 88% (B) 28% (C) 27% (D) 73% 50 ml. of a mixture of NH3 and H₂ was completely decomposed by sparking into nitrogen and hydrogen

Explanation:
it's so simple...do u want to know?
∴ % volume of NH3 in the original mixture =3650×100=72% Q. 50 ml of a mixture of NH3 and H2 was completely decomposed by sparking into nitrogen and hydrogen. 40 ml of oxygen was added and the mixture was sparked again.
