<h2>Atomic mass of Iridium is 192.25 amu</h2>

Step-by-step explanation:

Percentage abundance of Iridium-191 = 37.58 %

Mass of Iridium-191 = 191 amu

Percentage abundance of Iridium-193 = 62.42 %

Mass of Iridium-193 = 193 amu

We need to find atomic mass of Iridium.

Atomic mass of Iridium = 0.3758 x 191 + 0.6242 x 193

Atomic mass of Iridium = 192.25 amu

Atomic mass of Iridium is 192.25 amu
