Density of water

Therefore weights 20 g of water molecules.

So number of moles of water moles

1 mole occupies .

Therefore moles occupies , i.e., .

Auto photolysis of water involves breakage of chemical bonds as the result of transfer of light energy to these bonds of water. It involves release of oxygen as a byproduct and also releases hydrogen

To calculate the energy of the photon emitted, we use the formula that relates the energy of a photon to its wavelength: Where: - is the energy of the photon, - is Planck's constant, - is the speed of light, - is the wavelength of the light. Substituting the known values: Thus, the energy of the photon emitted during the transition is .
