Question

A student creates a calibration plot for serial dilutions of Cu(NO₃)₂. A graph of concentration in M (x-axis) versus absorbance (y-axis) gives a linear trendline of y = 0.345x - 0.11.

Copper(II) nitrate has a solubility of 83.5 g in 100 g of water. Calculate the percent error in the student's concentration.

Expert Solution

Step 1

Introduction :

Percent error is an expression to let know the difference between calculated value and actual value, these errors could happen due to the imprecision of equipment, measurement (human error or tool error), etc.
