### 6B.5

Hi, could someone help me approach this?

6B.5 Calculate the pH and pOH of each of the following aqueous
solutions of a strong acid or base: (a) 0.0146 m HNO3(aq); (b) 0.11 m
HCl(aq); (c) 0.0092 m Ba(OH)2(aq); (d) 2.00 mL of 0.175 m
KOH(aq) after dilution to 0.500 L; (e) 13.6 mg of NaOH dissolved
in 0.350 L of solution; (f) 75.0 mL of 3.5 3 1024 m HBr(aq) after
dilution to 0.500 L.

You can start to approach this by simply knowing that the addition of pOH and pH Is equal to 14 so (pOH+pH=14). So if you find the pH of the molecule using the molarity you found in each problem you can just subtract it to 14 and get pOH or vice versa.

How do you solve for (c)?
