The coefficient of that will show that the law of conservation of mass is obeyed by the equation would be 2.
<h3>What is law of conservation of mass?</h3>
It states that mass can neither be created nor destroyed in chemical reactions but can be converted from one form to another.
Thus, in the reaction represented by the equation below:
The coefficient of must be 2 in order for the equation to balance and thus, obey the law of conservation of mass.

Answer : The value of for the final reaction is, 184.09
Explanation :
The equilibrium reactions in aqueous solution are :
(1)
(2)
The final equilibrium reaction is :
Now we have to calculate the value of for the final reaction.
Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:
Now put all the given values in this expression, we get :
Therefore, the value of for the final reaction is, 184.09
