Q: A 1 molar solution of which of the the following salts has the highest pH?
A. NaNO3
B. Na2CO3
C. NH4CL
D. NaHSO4
E. Na2SO4

I think its a because NO3 would make a strong acid making more OH but im coufused totaly on how to find pH of salts

Highest pH, or lowest pH? Do you mean which is the strongest acid, or which is the weakest?

A strong acid has a low pH; for example HCl is around pH of 2. A high pH would indicate a base. A strong acid would not have more OH, so your wording is confusing.

which one of them is the strongest base?!

A strong base has weak conjugate acid ion.

Compare the relative strength of all the conjugate acid ions

Think along this line

this might be useful, although I'm sure you have something similar in your own textbook
