lab experiment- determination of copper in an aqueous sample using atomic absorption spectroscopy
0.1454 g of Copper was used to make the standard solution (1st volumetric flask)
The standard solution was diluted by a factor of 100.
into each of the 50-mL volumetric flasks, 5.00 mL of unknown solution was pipetted, and the solutions were made up to the mark with deionized water.
the equation of line is , y= 0.0271x + 0.1017
so, x and y intercept is x= -3.752767528
y= -0.009957
Calculate the concentration of copper in ppm, of the original unknown?
