A quantity of 5.0 g of an oxide of a metal was heated with charcoal, and so produced was absorbed in caustic soda solution whose weight increased by 2.2 g. The equivalent weight of the metal is
Options:
Answer:
C
Solution:
Weight gain = = 2.2 g, so oxygen taken from the oxide = 2.2 × (32/44) = 1.6 g. Metal mass = 5.0 - 1.6 = 3.4 g. Eq wt = (3.4/1.6) × 8 = 17. Hence (c).
