How do you calculate the % protonated of a weak acid/base?

you divide the change number by the concentration of the acid. Then you multiply by 100 if you want the percent.

You do the concentration of the conjugate over the concentration of the acid or base and then multiply by 100%.

then compare your % to 5%.

(changed concentration/ initial concentration ) (100%)

What exactly is the change number as mentioned in the above quote ?

What would CH3NH3Cl dissociate to produce?

you would get the ((change in concentration)/(initial concentration) )x100% and that is how you calculate it.
