How can I do the calculation here
 
Hi

Resolution = Vfs/2^n

Resolution = 3
Vfs = 2 V

find n

how I can find the n ... ?

If

Resolution = 3
Vfs = 5V

n = 1 - (lpg(3) / log(5))

is correct ?

No, that isn't correct.

We can solve for n in general:







Now, when given values for and just plug them into the above formula for n.
