acid and base

HNO3 is a strong acid.
You have 0.50 mole per liter HNO3. What is the concentration of H3O+ ions in the liquid concentration?

How do I find the solution to this question?

.50 moles per liter is .50 molar solution (0.50 M) correct? Strong acids completely dissociate, does that help ring a bell at all?

[H3O+] = 10^-pH or [H3O+] = antilog (- pH)
