An element has three stable isotopes. One has a mass number of 63 and

The atomic mass of an element is the weighted average of the mass of all of the isotopes.
63(0.5) + 65(0.3) + 67(0.2) = ?

200

64.4

blah shoot

Binch

64.4 is right

64.4

Educake am I right?

yea

Thanks for your help @anonymous (64.4)!

And everyone lese obviously!

64.4 is right
