In s 0.30 mol/L HNO3(aq) solution.
a) what is the concentration of nitric acid molecules.
b)what is the hydroxide ion concentration?
(a) In aqueous solution there are no HNO3 molecules. Only ions are present.
(b) (H^+)(OH^-) = 1E-14
(H^+) = 0.30. Solve for (OH^-)
Thank you! I am still confused about b)
NVM, i got it! thanks!
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?
