Interpretation Introduction Interpretation: Determine the number of naturally existing molecules of Cl 2 O having different masses and the masses of three molecules which are the most abundant. Explanation Calculate the number of naturally existing molecules of Cl 2 O having different masses with the two isotopes of chlorine and three isotopes of oxygen as follows: (1) C 35 l C 35 l O 16 (2) C 35 l C 35 l O 17 (3) C 35 l C 35 l O 18 (4) C 35 l C 37 l O 16 (5) C 35 l C 37 l O 17 (6) C 35 l C 37 l O 18 (7) C 37 l C 37 l O 16 (8) C 37 l C 37 l O 17 (9) C 37 l C 37 l O 18 So, there are nine molecules of Cl 2 O having different masses. The most abundant molecules are those which are composed of isotopes with higher abundance. Natural abundance of ( O-17 ) is the highest among the three isotopes of oxygen and the natural abundance of ( Cl-35 ) is higher than that of ( Cl-37 ) for chlorine. Therefore, C 35 l C 35 l O 16 ; C 35 l C 37 l O 16 ; C 37 l C 37 l O 16 are the most abundant molecules. Calculate the mass of C 35 l C 35 l O 16 as follows: m ( C 35 l C 35 l O 16 ) = m (Cl-35) + m (Cl-35) + m ( O − 16 ) = 2× ( 34
