The eamount of cadmium in a sample was determined using absorption spectroscopy as an analytical tecnique. Signals from a set of standards were measured and the resulting calibration curve was fit by a straight line with equation
signal=y-int + slope [Cd]
y-int=0.0158 +/- 0.0276 slope= 0.1791 +/- 0.0126
where [Cd] is measured in ppm. The unknown sample prodced a signal=1.341 +/- 0.076. Determine the concentration and uncertainty of cadmium in the unknown sample.

What is the final result?
