Explanation:
The given data is as follows.
= 3 M,
= ?
= 10 M,
= 10.0 ml
Therefore, calculate the volume of given solution as follows.
=
Now, putting the given values into the above formula as follows.
=
=
= 33.3 ml
or, = 0.033 L (as 1 ml = 0.001 L)
Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.
Molarity =
3 M =
mass = 3.96 g
Therefore, we can conclude that mass of NaOH is 3.96 g.
