    umm according to me ,the nuetrons and protons do not have the same weight..neutrons have wt slightly greater than 1 amu & proton is exactly 1 amu ..hence the sum of no. of protons & neutrons will not give the exact weight of the atom hence we use weighed values to calculate average atomic mass..

    because isotopes do not occur in 1:1 ratios, so you have to take into account the percentage at which they do exist in nature
