Particles reduced by a factor 1/e when the particles (density 8650 kg m3, cross section 24506 barns) incident upon an absorbing material. find the distance in which the particle beam is are thermal neutrons and the absorbing material is cadmium

Can someone explain to me how to do this problem ?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
