Question- The pKa of acetic acid, CH3COOH, is 4.74. A buffer solution was made using an unspecified amount of acetic acid and 0.30 moles of NaOOCCH3 in enough water to make 1.50 L of solution. The pH of the solution is 4.50.How many moles of CH3COOH were used?
Please carry out what you can and illustrate your work so I can follow. Thanks
