Answer:

116g

Explanation:

Given parameters:

Mass of A  = 88g

Mass of B₂  = 28g

Unknown:

Mass of AB produced  = ?

Solution:

The reaction expression is given as:

            2A + B₂ →  2AB

According to the law of conservation of matter "matter is neither created nor destroyed but changed from one form to another".

  In retrospect;

      Mass of A + Mass of B₂  =  Mass of AB

  Now insert the parameters and solve;

  Mass of AB  = 88g + 28g  = 116g
