I need to solve it , please i need correct answer

Set 2. The absorbance of an iron thiocyanate solution containing 0.00500mgFe/mL was reported as 0.4900 at 540nm. [a] Calculate the specific absorptivity , including units, of iron thyocyanate on the assumption that a 1.00cm cuvette was used. [b] What will be the absorbance if (1) the solution is diluted to twice its original volume and (2) the solution is placed in a 5.00cm cuvette
