Question

In the electrolysis of alkaline water a total of one mole of gas is evolved demote of water the compost bin

Answer 1

Answer: The amount of water decomposed would be 12 g.

Explanation:

Divide the while equation by 2

Total moles of gases evolved=

of gases are produced from 1 mole of water on decomposition

Then 1 mole of gases will be obtained from: moles of water that  moles

Mass of water = Moles of water × Molar mass of water
