A monoprotic weak acid, when dissolved in water, is 0.75% dissociated and produces a solution with a pH of 3.11. Calculate the Ka of the acid.
I really need a super-duper thorough step-by-step solution and the answer explanation. SHOW WORK!!!
Thanks!

1. A weak monoprotic acid is dissolved in water to produce a 0.026 M solution. The pH of the resulting solution is 3.65. Calculate the Ka for the acid. Just give the number to 2 significant figures. 2. You have a buffer solution composed of 2.00 mol of acid and 5.75 mol of the conjugate base. If the Ka of the acid is 2.6 x 10-4, what is the pH of the buffer? Just give the number.
a. Enough of a monoprotic acid is dissolved in water to produce
a 0.0163 M solution. The pH of the resulting solution is 2.51.
Calculate the Ka for the acid. Ka= ________
It's not 5.86 10-4. I tried it and it
wasn't correct.
b. The Ka of a monoprotic weak
acid is 6.61 × 10-3. What is the percent ionization of a 0.108 M
solution of this acid? Percent ionization= ___________
it's not 24.72 %. I tried it's also incorrect.
