Average atomic mass =(34.97×0.735+36.97×0.245)/(0.735+0.245)
=(25.70295+9.05765)/0.98
=35.47u

Answer:
Use the formula
average isotopic mass = [( Z1 × %age abundance) + ( Z2 × %age abundance)] / 100
Put values average isotopic mass = [(35×75.4) + (37×24.23)] / 100
After calculating average isotopic mass = 35.35
