pH = -log [H+] , so if pH = 3.0, you know 3.0 = - log [H+].
Now you want to get rid of the log from the right side of the equation so you can solve for the [H+], which is the concentration of the H+ ions in solution. To make this easier on myself, I divide both sides by -1, so the negative sign is on the side with the numerical value. So equation is now.
-3.0 = log [H+]
Apply exponents to get cancel out the log.
10 ^-3.0 = [H+]
Put that in your calculator and you should get [H+] = .001 M.
