Explanation:

The two naturally occurring isotopes of bromine are

81-Br (80.916 amu, 49.31%)   79-Br (78.918 amu, 50.69%).

The two naturally occurring isotopes of chlorine are

37-Cl (36.966 amu, 24.23%) and   35- Cl (34.969 amu, 75.77%).

Molar mass of BrCl molecule composed of  81-Br and  37-Cl.

Mass of 81-Br = 80.916 amu

Mass of  37-Cl = 36.966 amu

Molar mass of this BrCl molecule, = 80.916 amu + 36.966 amu

= 117.882 amu

Molar mass of BrCl molecule composed of  79-Br and  35-Cl.

Mass of 79-Br = 78.918 amu

Mass of  35-Cl = 34.969 amu

Molar mass of this BrCl  molecule = 78.918 amu + 34.969 amu

= 113.887 amu

Molar mass of BrCl molecule composed of  81-Br and  35-Cl.

Mass of 81-Br = 80.916 amu

Mass of  35-Cl = 34.969 amu

Molar mass of this BrCl molecule, = 80.916 amu + 34.969 amu

= 115.885 amu

Molar mass of BrCl molecule composed of  79-Br and  37-Cl.

Mass of 79-Br = 78.918 amu

Mass of  37-Cl = 36.966 amu

Molar mass of this BrCl molecule, = 78.918 amu + 36.966 amu

= 115.884 amu

The decreasing order of masses of for different BrCl molecules :
