Two substance `A_(2)(g) ` and `B_(2)(g)` are allowed to react to form either of `A_(2)B_(2)(l) , A_(2)B_(4)(g)` or both depending on relative amount.
Answer the following the following question, if 75 g `A_(2)` and `200g B_(2)` are mixed and no reactant is left.
[Given :At mass of A =25 , B=50]
Now `A_(2)B_(4)` is transferred to another container completey . At high temperature it is completely dissociated in its gaseous elements `A_(2)` and `B_(2)` . Find average molecular weight of gaseous mixture:
A. `(125)/(3)`
B. `(250)/(3)`
C. 125
D. 250
