A metal exhibits the valencies of 1 and 2. Its equivalent weight is 63.5 when it forms a metal oxide of formula . What mass of is needed for complete reaction with 15.9 g of MO?
Options:
Answer:
A
Solution:
In the metal is monovalent, so atomic mass = 63.5 × 1 = 63.5. MO molar mass = 63.5 + 16 = 79.5. MO + + ; 15.9 g = 0.2 mol oxide needs 0.2 mol = 0.2 × 98 = 19.6 g. Hence (a).
