A compound with a molecular weight of 292.16 was dissolved in a 5 ml volumetric flask.
Then withdrawn 1ml aliquot,placed in a 10 ml volumetric flask and diluted to the mark.The absorbency at 340 nm was 0.427 in a 1cm cuvet. The molar absorptivity for this compound at 340 nm is ε=6130
(M Inverse) (CM Inverse)
The Problem is (1)How can i approach to calculate the concentration of compound in the cuvet.
Secondly(2)What was the concentration of compound in the 5 ml flask ?
Third (3) How many milligrams of compound were used to make the 5 ml solution ?

Thanks in advance
