![3) A compound, X, with a molecular weight of
292.16 g/mol was dissolved in a 5.00 mL volumetric
flask and diluted to the mark. A 1.00 mL aliquot of
this was withdrawn, placed into a 10.00 mL
volumetric flask and diluted to the mark. The
absorbance at 340 nm was 0.427 in a 1.000 cm
cuvette. The molar absorptivity of X at 340 nm is
6130 M-¹ cm-¹
a) Using Beer's Law, what is the [X]
(concentration in molarity) for the diluted solution in
the cuvet ?
mmmmm
b) Use the dilution equation (McVc = MdVa) to
calculate [X] in the original 5.00 mL flask.
c) How many milligrams of X was used in the
original solution ? (Find total moles X using
