Put the steps in order to make 100 mL of 2.00×10-4M from 2.00×10-2 M solution of NaSCN. You have these materials to work with • 2.00x10-2 M solution of NaSCN • 5.00 mL pipet • 100.00 ml volumetric flask • various sized beakers : Check the calibration of a 5.00 mL pipettor. If it is not set to deliver within +/- 0.05 g, calibrate the pipettor. * Add solvent to the etch mark, cap and invert 20-30 times. : Pour some of the stock 2.00x10-2 M solution into a beaker. Transfer 1.00 mL of 2.00×10-2 M solution into a clean 100.00 mL volumetric flask using a calibrated 5.00 mL pipettor.
