" Determine the amount of sodium acetate needed to prepare 50.0 mL of acetic acid/sodium acetate buffer having a H of 5.0 using approximately 0.100 M acetic acid. Check the concentration of the acetic acid in the laboratory and use this exact concentration for your calculation. For acetic acid Ka= 1.8 x 105." The answer is 0.75g NaC2H3O2. But I need to show the equation steps. Any help?
