Just do 0.02 * 4 and you get 0.08 ml or 80 microliter
Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.

Moles of 
The balanced reaction for dissociation will be:

Thus for 4 moles of
, there is 1 mole of 
Thus moles of 
Molarity of 
Thus the molarity of the
solution = 0.06 M
b) Mass of
= 
Thus mass of
Wenzhou use is 3.13 grams.
