1) Which of the following has maximum number of Molecules? a) 20 g.

1.	1) Which of the following has maximum number of Molecules? a) 20 g. NO, b) 2gH c) 8 g. 0, d) 7g.N,
Answer» Explanation:1.Molecular MASS of NO : 14+16=30Moles of NO: 20/30=2/3=0.662.molecular mass of H : 1 Moles of H :2/1=23.molecular mass of O : 16Moles of O : 8/16=1/2=0.54.molecular mass of N : 14 Moles of N : 7/14=1/2=0.5Thus OPTION (B) hydrogen has maximum no. Of molecules
