The specific heat of a metal is 0.26. The chloride of the metal (always monomer) has its molecular mass 95. The volume of hydrogen gas that 1.2 g of the metal will evolve at 0°C and 1 atm, if it is allowed to react with excess of an acid, is
Options:
Answer:
B
Solution:
Dulong-Petit: atomic mass ≈ 6.4/0.26 = 24.6. Chloride MClₓ = 95 gives 35.5x ≈ 70.4, so x = 2 and exact atomic mass = 95 - 71 = 24; Eq wt = 12. Equivalents of metal = 1.2/12 = 0.1 = equivalents of H₂ = 0.05 mol. Volume at STP = 0.05 × 22.4 = 1.12 L. Hence (b).
