Prepare a calibration curve to determine the Pb content in a well water sample using atomic absorption spectrophotometry; the following data were recorded:

% T	100	75.2	56.6	42.5	31.9	24.6	13.8
ppm Pb	0	0.2	0.4	0.6	0.8	1.0	1.4

A 50 mL aliquot of well water is taken and diluted twice, the% T reading is taken and a value of 40.6% is recorded.

Calculate the ppm of Pb in the well water.
