Answer:
Will the electronegativity of barium be larger or smaller than that of strontium? Explain. EN of Ba (0.89) is smaller than EN of Sr (0.95). Because of larger size and more inner core e- shielding, Barium will more readily share its valence electron in the 6s sublevel than Sr will share it valence e- in the 5s sublevel.

Answer:
The value is
Explanation:
From the question we are told that
The mass of NaOH is
In the question DI (stands for de-ionized water )
So the number of moles of NaOH present in the given mass is
Here Z is the molar mass of NaOH with value
So
Given that the volume of the flask is V = 1 L then we can evaluated the concentration as
=>
=>
