Is there an easy way to calculate pH when given the M concentration of a compound as well as its amount in liters?

You have to focus on the concentration of the H+ ions, not the molarity of the compound. For exampe, a 1M H2SO4 has twice as many H+ ions compard to a 1M HCl. So the pH would be quite different for these two solutions.

I'm afraid there is no guranteed short cut that is fool proof

pH= - lg [H+]
[H+] - concentration of ions
