The mass of potassium dichromate crystals required to oxidise $750\, cm^3$ of 0.6 M Mohr's salt solution is : (Given molar mass potassium dichromate = 294, Mohr's salt = 392)

An organic compound having molecular mass 60 is found to contain C = 20%, H = 6.67% and N = 46.67% while rest is oxygen. On heating it gives $NH_3$ alongwith?? solid residue. The solid residue give violet colour with alkaline copper sulphate solution. The compound is :

In an organic compound of molar mass $108 g$ $mol ^{-1} C , H$ and $N$ atoms are present in 9: 1: 3.5 by weight. Molecular formula can be :
