a naturally occurring sample of copper consists of 69.2%of ^63 cu and 30.8%of ^65 cu. The relative mass of ^63 cu is 62.93 and that of ^65 cu is 64.93. find the atomic mass a naturally occurring sample of copper

(69.2/100)×62.93 + (30.8/100)×64.93
=(43.54)+(19.99)
=(63.53)amu
This is atomic masd of naturally occuring sample of copper
=(43.54)+(19.99)
=(63.53)amu
