Combustion of 0.42g of a compound gave 0.924gCO_(2) and 0.243g H_(2)O. Due to distillation of 0.208g of compound with NaOH, ammonia evolved required 30mL of (N)/(20)H_(2)SO_(4) for complete neutralization. Vapour density of the compound is 69.5. What is the percentage composition of hydrogen in the compound?
