1 mole of photons contain 
photons (Avogadro number). This means that 3.0 moles of photons contain
photons.
The wavelength of the light in the problem is
, so the frequency is
The energy carried by a single photon is
where
is the Planck constant, while f is the frequency. Since this is the energy carried by a single photon, the energy carried by 3.0 moles of photons will be the energy of the single photon multiplied by the total number of photons:
which corresponds to E=536 kJ.

Answer:
0.5 g
Explanation:
The half-life of a radioactive isotope is the time it takes for a certain amount of that isotope to halve.
In this case, we have an isotope of Americium-241, which has a half-life of
This means that after 1 half-life (432 years), there will be an amount of americium equal to half its initial amount.
In this problem, the initial amount of americium is
Therefore, after 432 years (1 half-life), the amount of americium left will be half:
