Answer: 1.14mol
Nitrogen molar mass=14g/mol

The strongest and most penetrating radiations are the gamma rays. Any material that can prevent the movement of these rays can halt alpha and beta particles too.
An aluminium shield is made up of multiple layers of aluminium stacked together and it provides enough resistance.
