How many molecules of water are proud you was from 19.2 g of O2

Answer : The number of moles of water are,

Explanation : Given,

Mass of = 19.2 g

Molar mass of = 32 g/mol

The balanced chemical reaction will be:

First we have to calculate the moles of .

Now we have to calculate the moles of .

From the balanced chemical reaction, we conclude that:

As, 2 moles of react to give 2 moles of

So, 0.6 moles of react to give 0.6 moles of

Now we have to calculate the number of moles of .

As, 1 mole of molecule occupies molecules of

So, 0.6 mole of molecule occupies molecules of

Therefore, the number of moles of water are,
