PLEASE ANSWER BOTH QUESTIONS. THANK YOU

b. Beer's Law is a limiting law where the absorbance (A) is directly proportional to concentration (C) at a given wavelength of light through the absorptivity (a) of the material, A=abC, where b represents the path length. If the absorptivity of the material is 988L(molcm)1 and the path length is 10.00mm, what is the absorbance of a solution with a concentration of 3.804104M ? c. The heat (q) given off or absorbed in a chemical reaction can be determined through the temperature change: q=mCsT where m is the mass of the system, Cs the specific heat capacity and T the temperature difference. What is the heat given off by the neutralization of sodium hydroxide by hydrochloric acid if the mass of the system is 95.063g, the specific heat capacity is 4.184J(gC)1 and the initial and final temperatures are 68.9F and 88.2F, respectively
