Answer:
Dissociation NH3 0.10 M : 1.2%
Dissociation NH3 0.010 M : 3.9%
Dissociation CH3NH2 0.10 M : 6.5%
Explanation:
Hello!
To calculate the percentage of dissociation it is necessary:
Pose the balanced chemical equation.
Pose the equilibrium constant.
Calculate the value of "x"
Calculate the percentage of dissociation.
By having the concentrations given two significant figures we express the dissociations with the same amount of significant figures.
