a) 2.b) 3.c) 4.d) 5.e) 6.Please show the full solution.......
The pH of a 1 L solution containing 100 mL of 1M acetic acid and 4.1g of sodium acetate (formula weight 82g/mol; pK=4.76) is...

a) 2.76
b) 3.76
c) 4.76
d) 5.76
e) 6.76

Please show the full solution...

Use Henderson Hasselbach Equation

pH = pKa + log [base]/[acid]

[base]=(4.1/82)/0.100L = 0.5

pH = 4.76 + log (0.5)/1

pH = 4.46
