The total cross section for a nuclear reaction p + Y is 87.0 millibarn. Calculate the number of reaction products if this reaction should be studied at an accelerator facility using a beam current of 277.0 nA, a target in the form of a slim slab made of element Y with length 1.100 cm, width 3.70 cm, and thickness 1.70 mm, and having a density of 3.11 g/cm3 . How many reactions would have occurred if the target was irradiated for 3 hours. Assume element Y has an atomic mass of 75.0 u
