Fifty millilitre of a mixture of NH3 and...

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.
