Question

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.
x and y intercept is x= -3.752767528
y= -0.009957

Calculate the concentration of copper in ppm, of the original unknown?​

Answer 1

Explanation:

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.

x and y intercept is x= -3.752767528

y= -0.009957

Calculate the concentration of copper in ppm, of the original unknown?
