Minchanka [31]

Answer:

151.94 u

Explanation:

The atomic mass of Eu is the <em>weighted average</em> of the atomic masses of its isotopes.

We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its <em>percent abundance</em>).

The atomic masses of Eu-151 and Eu-153 are 150.92 u and 152.92 u, respectively.

Set up a table for easy calculation.

0.4803 × 150.92 u =  72.472 u

0.5197 × 152.92 u  = <u> 79.473 u </u>

                 TOTAL = 151.94  u
