If a graph is given for a cuvette using a 1.00 cm , predict the graph if a 2.0 cm diameter test tube and a 0.50cm test tube are used.
The points for the 1.00cm test tube are
(0,0),((2E5),0.1), ((4E5),0.2),
((6E5),0.4), ((8E5),0.5)...linear graph
X=Concentration (molars)
Y=Absorbance
I am not sure where to start, but for the 2.0 would the absorbance be doubled, and for the 0.50 would the absorbance be half of what it is? Thanks.

DrBob222,
Yes, just go through the graph and double or half the values. This will be so if the curve you have is a straight line. If the sample does not obey Beer's Law and it is curved (nonlinear), that will not be true for the nonlinear portion of the graph.
