What is the atomic mass of barium due to?

Answer 1

Wyatt Adkins

Atomic mass of barium is around #137.327 u ~~2.28*10^-22 g#

The average of all barium isotopes' mass rounds up to #137.327 u#.

#1 u ~~ 1.66*10^-24 g#

Therefore, the atomic mass of barium is #137.327 * 1.66*10^-24 =2.28*10^-22 g#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
