Chemistry - Stoichiometry Question with Solution | TestHub

A definite volume of pure ammonia ( ${\mathrm{NH}}_3$ ) gas is passed through a series of electric sparks by which the volume becomes 90 ml . The increase in volume is due to formation of nitrogen $\left({\mathrm{N}}_2\right)$ and hydrogen $\left({\mathrm{H}}_2\right)$ gases. All the gases finally present are washed with dilute sulphuric acid solution, by which the volume of gases becomes 80 ml . All the volume are measured at the same temperature and pressure. Which of the following statement(s) is /are correct regarding the original ammonia sample?
