An organic compound weighing 6g on heating with NaOH gave NH3 which is neutralised by 200mL of 1N of HCl. Percentage of nitrogen in it is 1) 12% 2)60% 3)46.67% 4)26.67% I want the answer with detailed calculation.

let the organic compund be represented by X
x +NaOH ------NH3 +HCL----NH4Cl
mole of NH3 formed is 200*1/1000=.2mole
weight of nitrogen in NH3=.2*14=2.8gm
therefore weight in NH3 and weight of nitrogen in organic compound will be same
thus the percentage of nitrogen in organic compound =(2.8/6)*100=46.67%
