Determine the concentration of copper in the saturated copper (II) tartrate solution.

Question

Saturated Solution: 0.616

My equation from graph: 13.389x-0.0342

Answer 1

What is the graph? What did you plot on the x and y axes? Was it concentration vs absorbance? If so, is 0.616 the absorbance reading? I will assume this is the case, but you MUST tell the reader this information. If this is NOT the case, state so in the comment section.

y = 13.389 x - 0.0342 is of the form y = mx + b which is the equation for a straight line.

y = absorbance

x = concentration (units not given)

Solving for x (concentration) we have

0.616 = 13.389 x - 0.0342

x = 0.0486 units (the units might be M, g/ml, mM, nM, etc. can't tell since you didn't say in the question)
