The volume of ammonia obtained by the combination of 10 mL of N_(2) and 30 mL H_(2) is _________.

10 " mL of " a gaseous organic compound containing C, H and O only was mixed with 100 " mL of " O_(2) and exploded under condition which allowed the H_(2)O formed to condense. The volume of the gas after explosion was 90 mL. On treatment with KOH solution, a further contraction of 20 mL in volume was observed. The vapour density of the compound is 23. All volume measurements were made under the same condition. Q.The volume of unreacted O_(2) is
