Step-by-step explanation:
From the question we are told that
The mass of NaOH is
![m= 0.8036 g](https://img.qammunity.org/2021/formulas/chemistry/college/d034csclo6uih8amlxtjk9e0fya30z0b2i.png)
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
![C = (n)/(V)](https://img.qammunity.org/2021/formulas/chemistry/college/o42clxf8mjvexlw689yt317ed9it87ec5u.png)
=>
![C = (0.02009)/(1)](https://img.qammunity.org/2021/formulas/chemistry/college/vwg109bp78jnrjdwt9vyirp7uesy6ywa6y.png)
