Explanation:

Atomic Mass Matching


In this exercise, we will match the elements with their respective atomic masses. Below are the elements provided:



  • Cobalt (Co): The atomic mass of cobalt is approximately 58.93 u.

  • Platinum (Pt): The atomic mass of platinum is about 195.08 u.

  • Mercury (Hg): The atomic mass of mercury is approximately 200.59 u.

  • Arsenic (As): The atomic mass of arsenic is around 74.92 u.


Here’s the completed matching:



  1. Cobalt - 58.93 u

  2. Platinum - 195.08 u

  3. Mercury - 200.59 u

  4. Arsenic - 74.92 u


Knowing the atomic masses is crucial for understanding chemical reactions and stoichiometry in chemistry.
