is there any different from calculating the 0.01 M NH4Cl?

you can't calculate the pH of NaCl.... because it won't change the pH at all.
pH means power of hydrogen. It's just basically the concentration of hydrogen (technically hydronium) atoms in water. Somethign lowers the pH when it adds hydrogen atoms to the water- this is called an acid. It raises it when it takes hydrogen atoms away.
An ionic compound will affect pH if it has hydrogen, H+, or Hydroxide ions OH-
For instance, HCl will affect the pH because it has H+ ions.
NaCl, salt, has neither, and will not affect the pH

That's untrue to say that a compound needs hydronium or hydroxide ions to have a non-neutral pH, Guy Above Me.
