What is the sum of the molecular weight of diatomic gas formed by given reactions?

$K Cl O_{3} (s) Δ (P)$

$N H_{4} N O_{2} (s) Δ (Q)$

$B_{2} H_{6} Hy d ro l ys i s (R)$

$N a Cl + M n O_{2} H^{+} /Δ (S)$

The diatomic gases formed in each reaction and their molecular weights are:

(P): Thermal decomposition of KClO₃ yields O₂ gas ( $M . W . = 32$ ).

(Q): Heating NH₄NO₂ produces N₂ gas ( $M . W . = 28$ ).

(R): Hydrolysis of diborane (B₂H₆) releases H₂ gas ( $M . W . = 2$ ).

(S): Reaction of NaCl and MnO₂ in an acidic medium evolves Cl₂ gas ( $M . W . = 71$ ).

$T o t a lS u m = 32 + 28 + 2 + 71 = 133.00$
