Answer : The volume of NaOH stock solution used should be, 250 ml
Solution :
According to the neutralization law,
where,
= molarity of NaOH solution = 0.50 M
= volume of NaOH solution = 3.0 L
= molarity of NaOH stock solution = 6.0 M
= volume of NaOH stock solution = ?
Now put all the given values in the above law, we get the volume of NaOH stock solution.
(1 L = 1000 ml)
Therefore, the volume of NaOH stock solution used should be, 250 ml
The correct answer is A) the number of electrons that fill the outer shell.
