How many moles of h2o will be produced from 42.0g of h2o2

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
