Question

Among  g (each) of the following elements, which one will have the highest number of atoms? Element: Pb, Po, Pr and Pt

Canvas Classes · Accepted Answer

Strategy:
 The number of atoms is proportional to the number of moles. For a fixed mass, the element with the lowest atomic mass will have the highest number of atoms.

Step 1: Compare atomic masses
- Lead (Pb) 
- Polonium (Po) 
- Praseodymium (Pr) 
- Platinum (Pt)

Step 2: Conclusion
Since Praseodymium has the lowest atomic mass, it yields the most atoms per .
