The procedure for the gravimetric determination of Ca includes the following instructions which require measurement of material. Which measurements need to be precise and which can be approximate? If you think the answer is somewhere in between, explain your thinking.  Add 5 mL concentrated HCl to clean the crucible. Dry the crucibles to constant mass. Dry the unknown sample for 1 hour. Weigh (to the nearest 0.1 mg) an amount between 1.6 and 2.0 g into a 400 mL beaker. Add 2-4 mL concentrated (12 M) HCl solution. Dilute the sample in a 100.0 mL volumetric flask. Transfer 25.00 mL of the stock solution to each of three beakers. Add 25 mL ammonium oxalate to each beaker.
