1.O complexo formado entre Cu(I) e 1,10-fenantrolina possui absortividade molar de 7000 L.mol-1.cm-1 a 435 nm, que o mximo de absoro. Calcule:

a)a absorbncia de uma soluo 8,50 x 10-5 mol.L-1 do complexo medida em uma clula de caminho tico de 1,00 cm a 435 nm.

b)a transmitncia percentual da soluo do item "a".

c)a concentrao de uma soluo que em uma clula de 5,00 cm apresente a mesma absorbncia da soluo do item "a".

d)o caminho tico que deve ser empregado com uma soluo 3,40 x 10-5 mol.L-1 do complexo para que a absorbncia seja igual lida no item "a".
