There's a little bit of a process to this calculation. The idea, however, is to convert the Pico meters to the wavelength of this gamma radiation into an energy. So we'll convert PICO meters and two meters and then remember that the energy of a single photons equal to Planck's constant times the frequency but the frequency.
It's the speed of light, divided by the wavelength. The wavelength is what we just calculated up above. So we get an energy of 2.28 I'm standing the negative 14 Jules. Permission or perf otan prevent that occurs. So we have we have this many, Jules prevent.
We could multiply it by avocados number to figure out the Jules per mole of event and then we can use equals m C squared. Knowing the energy now per mole. In order to calculate the mass defect per mole of photons that were emitted, we get 1.53 10 to the negative seven kilograms
What is metastable state?
Metastable state, in physics and chemistry, particular excited state of an atom, nucleus, or other system that has a longer lifetime than the ordinary excited states and that generally has a shorter lifetime than the lowest, often stable, energy state, called the ground state.
A metastable state may thus be considered a kind of temporary energy trap or a somewhat stable intermediate stage of a system the energy of which may be lost in discrete amounts. In quantum mechanical terms, transitions from metastable states are “forbidden” and are much less probable than the “allowed” transitions from other excited states.
