For each solution, determine the [H3O*], [OH], and pH. Show problem set ups and set the answers with
correct sig figs. Provide correct units where anplicable, Assume Ky = 1.00 x 10" exactiy.
A.0.35 M HN03
Answers: [H3O*] = 0.35 M; [OH] = 2.9 x 10-14 M; pH = 0.46
B. A solution that is 0.045 M HCIO4 and 0.068 M HCI
d pecent
K-49x10
Answers: [H3O*] = 0.113 M; [OH]= 8.85 x 10-14 M; pH = 0.947
C. A solution that is 0.655% HNO, by mass (i.e. in a 100-g solution, HNO3 makes up 0.655 g). The density
of the solution is 1.01 g/mL. [Hint: Consider a solution that weighs exactly 100. g (3 sig figs)]
