Show calculations for obtaining correct answer of 7.3 hours.
1 mole = 6.022* 10^23 molecules of product.
As 1 photon leads to 1 molecule of product, amount of photons needed = 6.022*10^23
Rate of photon delivery = 2.3*10^19 photons/sec
So time needed = 6.022*10^23/(2.3*10^19) seconds = 2618 seconds =7.27 hours 7.3 hours (rounded)
