An organic compound containing C, H, N and O gave the following result

1.	An organic compound containing C, H, N and O gave the following results on analysis : (i) 0.25 g of the compound gave 0.368 g of CO_2 and 0.205 g of H_2 O (ii) The same weight of the compound gave 31.2 mL of N_2at S. T. P. Calculate the percentage composition of the compound.
Answer» Solution :(i) Percentage of C `= (12)/( 44) xx ( " Wt. of" CO_2 ) /( "Wt. of COMPOUND") xx 100` `= (12)/( 44)xx ( 0.368)/( 0.25) xx 100` `= 40.14 %` (ii) Percentage of `H = (2)/( 18) xx ("Wt. of water")/( " Wt. of compound" xx 100` `= (2)/( 18) xx (0.205)/( 0.25) xx 100 = 9.11 %`
