(a) In aqueous solution there are no HNO3 molecules. Only ions are present.
(b) (H^+)(OH^-) = 1E-14
(H^+) = 0.30. Solve for (OH^-)
(b) (H^+)(OH^-) = 1E-14
(H^+) = 0.30. Solve for (OH^-)

is it true that at 20ºC, 100g = 100mL （for water)

How do we determine the specific gravity of a solution? and what unit is it in?

How did you know that (H^+)(OH^-) = 1E-14?
And how did you know that (H^+) = 0.30 (Other than knowing that it was given from the questions, how would you know if that was the concentration of the hydrogen ion?)
