50 " mL of " a mixture of `NH_3` and `H_2` was completely decomposed into `N_2` and `H_2` by sparking. 40 " mL of " `O_2` was then added and the mixture was sparked again. After cooling the mixture was shaken with alkaline pyrogallol and a contraction of 6 mL was observed. Calculate the percentage of `NH_3` in the original mixture.

Fifty millilitre of a mixture of NH_3 and H_2 was completely decomposed into N_2 and H_2 by sparking. Forty millilitre of O_2 was then added and the mixture was sparked again. After cooling, the mixture was shaken with alkaline pyrogallol and a contraction of 6 ml was observed. Calculate the percentage of NH_3 in the original mixture.
