The specific heat of a metal is 0.11. The chloride of the metal (always monomer) has its molecular mass 127. The volume of hydrogen gas that 1.4 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:
C
Solution:
Dulong-Petit: atomic mass ≈ 6.4/0.11 = 58.2. Chloride = 127 gives 35.5x ≈ 68.8, so = 2 and exact atomic mass = 127 - 71 = 56; Eq wt = 28. Equivalents of metal = 1.4/28 = 0.05 = equivalents of = 0.025 mol. Volume at STP = 0.025 × 22.4 = 0.56 L. Hence (c).
