A quantity of 3.7 g of an oxide of a metal was heated with charcoal, and CO₂ so produced was absorbed in caustic soda solution whose weight increased by 1.0 g. The equivalent weight of the metal is
Options:
Answer:
C
Solution:
Weight gain = CO₂ = 1.0 g, so oxygen taken from the oxide = 1.0 × (32/44) = 0.727 g. Metal mass = 3.7 - 0.727 = 2.973 g. Eq wt = (2.973/0.727) × 8 = 32.7. Hence (c).
