Answer 1

I have submitted the first four sub-parts, please post multiple question to get the remaining answers

            $a) CH_3COOH \rightleftharpoons CH_3COO^- + H^+$

Initial              1.54M                       0                   0

Final             (1.54-x)M                   xM                xM

Ka of acetic acid = 1.8 * 10^(-5)

$Ka = \frac{[CH_3COO^-][H^+]}{[CH_3COOH]}$

$1.8 * 10^{-5} = \frac{x^2}{1.54-x}$

assuming (1.54-x) is approximately equal to 1.54
