The relative average deviation of 0.07% is very low, which indicates that the precision was good. This means that the reported molarity is reliable.Auto reject call samsung s20Since the same sample cell is used several times, it is important to rinse the sample cell quantitatively with the next unknown sample solution to be measured. Determine if Beer's Law is observed by plotting (see sample graph attached in the informal lab sheet) Absorbance at 595 nm (A, y-axis) vs. concentration (ppm, x-axis). The standard
