Answer:

The value is
C = 0.02009 \ M

Step-by-step explanation:

From the question we are told that

The mass of NaOH is
m= 0.8036 g

In the question DI (stands for de-ionized water )

So the number of moles of NaOH present in the given mass is


n = (m)/(Z)

Here Z is the molar mass of NaOH with value
Z = 40 \ g/ mol

So


n = (0.8036)/(40)


n =0.02009 \ mols

Given that the volume of the flask is V = 1 L then we can evaluated the concentration as


C = (n)/(V)

=>
C  =  (0.02009)/(1)

=>
C  =  0.02009 \ M
