Answer : The number of moles of water will be, 1.235 moles
Solution : Given,
Mass of = 42 grams
Molar mass of = 34 g/mole
First we have to calculate the moles of
Now we have to calculate the moles of water.
The balanced chemical reaction will be,
From the balanced reaction, we conclude that
As, 2 moles of decomposes to give 2 moles of water
So, 1.235 moles of decomposes to give 1.235 moles of water
Therefore, the number of moles of water will be, 1.235 moles
