How many grams of sodium acetate molar mass 82.03 must be added to 1.00 L pf a 200 M acetic acid solution to form a buffer of 4.20?

I think you meant .2M, right?
PH=pKa+log(Base/Acid) pKa=-log(Ka)= 4.74.2=4.7+log(x/.2)
-.5=log(x/2)
10^-.5=x/.2
x=.0632M
.0632M X 1L X 82.03g/mol = 5.19g

Why pH of sodium acetate is always adjusted with glacial acetic acid only?
in order to form acetate/acetic acid buffer solution!
Is an example of a buffer solution a mixture of acetic acid and sodium acetate?
Yes it is. pKa=4.77 so it is well buffering round pH 4.8 (4.1 ... 5.5)
What are some examples of a buffer?
Some examples of a buffer are mixture of ammonium hydroxide with ammonium chloride & mixture of acetic acid and sodium acetate.
What are three common buffer systems?
-Acetic acid and sodium acetate -Citric acid and sodium salts -Phosphoric acid and sodium/potassium salts
How about prepare a solution of a 0.1N acetate buffer?
The following table is extracted from the Internet:* For pH=3: mix 982,3 mL 0,1 M acetic acid with 17,7 mL 0,1 M sodium acetate* For pH=4: mix 847,0 mL 0,1 M acetic acid with 153 mL 0,1 M sodium acetate* For pH=5: mix 357 mL 0,1 M acetic acid with 643 mL 0,1 M sodium acetate* For pH=3: mix 52,2 mL 0,1 M acetic acid with 947,8 mL 0,1 M sodium acetate

Sodium acetate buffer?
can I make sodium acetate buffer 0.2M Ph=5 whit sodium acetate buffer 3m Ph=5 solution?

Calculate the pH of a 0.01M solution of sodium acetate?
0.1 molar solution around 8.9 at 25C Per Merck Index...

What is the pH of a buffer made from 10 ml of sodium acetate mixed with 1 ml of acetic acid?
In order to find the pH, one needs to know the CONCENTRATIONS of the sodium acetate and the acetic acid. Knowing the volumes is not enough information.

Sodium acetate from glacial acetic acid?
The reaction is: CH3COOH + NaHCO3 = CH3COONa + H2O + CO2 Slowly heating the aqueous solution you can obtain crystallized sodium acetate.
Solution made from a weak acid and its conjugate base that neutralizes small amounts of acids or bases added to it?
Acetic acid, CH3COOH, and Sodium Acetate, (CH3COOH-)(Na+).
Is sodium acetate solution a metal?
No. Sodium acetate solution is a homogeneous mixture, which is a solution. Sodium acetate is an ionic compound formed from sodium ions and acetate ions. Sodium in sodium acetate no longer has the properties of sodium metal.
What is the calculation in finding the pH of a L solution to which has been added W ml of MM acetic acid and W ml of MM sodium acetate?
pH = pKa + log [sodium acetate]/[acetic acid] = Henderson Hasselbalch equation
