Answer:
the average atomic mass of an element is the weighted average of the masses of its naturally occurring isotopes
Explanation:
butbut the abundance of isotopes of each element may differ so the abundance of all this isotopes are taken into consideration while calculating the atomic mass
atomic mass=(9×50\100)+(10×50/100)
=4.5+5= 9.5 amu
