Carbon dioxide is the atmospheric compound that is
responsible (after it have dissolved in water) for both the general acidity of
normal rainwater and the acidity of much soil. Natural rain water is slightly
acidic because carbon dioxide combined with water in the air forms carbonic
acid, which is a weak acid.

Kindly find the attached presentation.
Because M = mol/L or mL. 15.0 x 0.350/42.0 = M
Answer:
9.93
Explanation:
Your value for Kw is incorrect. The correct value is 5.48 × 10^-14.
pH + pOH = pKw
3.30 + pOH = -log(5.84 × 10^-14) = 13.23
pOH = 13.23 - 3.30 = 9.93
The pOH of the solution is 9.93.
