A Salt (X) on heating in air produces a gas (A).

The salt, on reacting with dilute $$\ce{H_2{SO}_4}$$ produces a gas (B) and a blue colored solution (C).

Gas (A), when passed through the aq. solution of (B), produced a yellowish white precipitate (D).

Salt gives a blue colored bead in oxidizing flame, and colorless bead in reducing flame, in Borax Bead test.

Find the sum of the molecular masses of A, B, C, D, and X.
