Questions\ The literature value for the molar absorbtivity coefficient for the iron-phenanthroline complex synthesized is

11,100L*mol^(-1)*cm^(-1)

. The slope from your plot is equal to

a*b

or molar absorbtivity ) if concentration is in molarity. How does your experimentally determined value compare to this?\ Compare your determined iron amount with the value reported on the vitamin bottle.\ What might be the main sources of uncertainty or error in this determination?
