When copper oxide is strongly heated with hydrogen, it reduces to copper. The loss in its weight is 14.9 g and the weight of water formed was 16.78 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 from the oxide = 14.9 g. Mass of hydrogen in the water = 16.78 - 14.9 = 1.88 g. Equivalent weight of O = 14.9 × 1.008/1.88 = 7.989. Hence (b).
