What is the exact atomic weight of the metal?
Options:
Answer:
A
Solution:
Equivalents of Cl = 108/108 = 1, so mass of Cl = 35.5 g and mass of metal = 44.5 - 35.5 = 9 g, giving E = 9. By Dulong-Petit, approximate atomic weight = 6.4/0.24 ≈ 26.7, so valency = 26.7/9 ≈ 3. Exact atomic weight = 9 × 3 = 27, matching (a).
