Calculate correct grams of Sodium Acetate to the desired volume then titrate pH with glacier acetic acid.

Assuming you want 0.1M of dissolved acetate, it is not possible to prepare the solution you mention due to the acid-base properties of the acetate system. If you dissolve 0.1M of acetic acid in pure water, the pH is ~2.9. Then if you add NaOH the pH will be higher.

You can however make a solution of pure acetic acid at pH 2.7 by adding 0.2M of acetic acid to pure water.

Alternatively you can prepare a solution of Cl- and acetate by dosing HCl to lower the pH

Thank you both for your answers..

It would be of benefit to know the background why you try to mix up sodium acetate 0.1M at pH 2.7 [which doesn't make sense to me if you want to use it presumably as a 'buffer' or as perhaps as a HPLC-buffer (where you better should use ammonium-formate (pH2.7-pH4.7)].
