Correct answer: 45

Mol.wt.45g CH ₃ CH ₂ NH ₂ NaNO ₂+ HCl H ₂ O CH ₃ CH ₂- OH + 14 ~g ~N ₂ given : N ₂ evolved is 2.24 L i.e. 0.1 mole. i.e. CH ₃ CH ₂ NH ₂ (ethyl amine) will be 4.5 ~g (=0.1 ~mole ) Hence the answer =45 10⁻¹ ~g

( X g ) of ethylamine is subjected to reaction with ( NaNO ₂ / HCl ) followed by water; evolved dinitrogen gas which occupied (2.24 ~L ) volume at STP. ( X ) is ( ) ( 10⁻¹ ~g ).
