Naturally occurring chlorine is composed of two isotopes: 75.76 % Cl-35 (mass of 34.9688 amu) and 24.24 % Cl-37(mass of 36.9659 amu). Naturally occurring oxygen is composed of three isotopes: 99.757% O-16 (mass of 15.9949 amu), 0.038% O-17 (mass of 16.9991 amu), and 0.205% O-18 (mass of 17.9991 amu). The compound dichloromonoxide is composed of two chlorine atoms and one oxygen atom bonded together to form the Cl2O molecule.
Give the masses of the three most abundant Cl2O molecules.
