Hello, I am taking chemistry class 1046 lab and I have a homework situation.
the homework is about (Analysis
of Copper in Brass Sample) In the data result I need to get the morality of Cu2+ as read from the standard curve, and the absorbance of Y and X is morality. Calculate the morality of Know solution knowing their absorbance.
the data: Absorbance value obtained 0.229 from trial #1 and 0.301 from trial #2. Can you help me please?
Conc. (ppm) absorbance
Absorbance vs. Concentration
0,2068x + 0,0084
