When an oxide of a metal is strongly heated with hydrogen, it is reduced to the metal. The loss in its weight is 15.87 g and the weight of water formed is 17.87 g. What is the equivalent weight of oxygen, taking the equivalent weight of hydrogen as 1.008?
Options:
Answer:
B
Solution:
Loss in weight = oxygen lost = 15.87 g. Mass of hydrogen in the water = 17.87 - 15.87 = 2.00 g. Equivalent weight of O = 15.87 × 1.008/2.00 = 8.00. Hence (b).
