Ring structure is defined as the structure in which one or more series of compounds are joined or linked to form a ring.  Ring can exist in different sizes such as cyclopropane (small ring: three carbon atoms) and cyclohexane (large ring: six carbon atoms).

In ring structure, there is only carbon atoms linked with hydrogen atoms which are identified by the linkage of two lines.

See the attached figure: cyclopropane (unlabelled atoms are carbon atoms with hydogens).

Thus, in ring structure, an unlabelled atom at an angle where two lines joined assumed to be carbon atom.

Answer:

0.034 M is the molarity of sodium acetate needed.

Explanation:

The pH of the buffer solution is calculated by the Henderson-Hasselbalch equation:  

pH = pK_a + \log \frac{[A^-]}{[HA]}

Where:  

pK_a= Negative logarithm of the dissociation constant of a weak acid  

[Ac^-] = Concentration of the conjugate base  

[HA] = Concentration of the weak acid

According to the question:

HAc(aq)\rightleftharpoons Ac^-(aq)+H^+(aq)

The desired pH of the buffer solution = pH = 5.27

The pKa of acetic acid = 4.74

The molarity of acetic acid solution = [HAc] = 0.01 M

The molarity of acetate ion =[Ac^-] = ?

Using Henderson-Hasselbalch equation:  

5.27= 4.74 + \log \frac{[Ac^-]}{[0.01 M]}

[Ac^-]=0.0339 M\approx 0.034M

Sodium acetate dissociates into sodium ions and acetate ions when dissolved in water.

NaAc(aq)\rightarrow Na^+(aq)+Ac^-(aq)\\

[Ac^-]=[Na^+]=[NaAc]= 0.034M

0.034 M is the molarity of sodium acetate needed.
