Passage / Comprehension
A quantity of 0.4 g of oxygen and 4.0 g of a halogen combine separately with the same amount of metal.
What is the equivalent weight of halogen if the valency of element in the halide is twice that in oxide?
Options:
Answer:
A
Solution:
If the metal's valency in the halide is twice that in the oxide, its equivalent weight in the halide is halved, so the same mass of metal supplies twice as many equivalents: 2 × 0.4/8 = 0.1 eq. Then E(halogen) = 4.0/0.1 = 40, matching (a).
