Determine the effect of the following errors on the measured absorbance for a pink colored 0.50 M solution of Cobalt (II) chloride, CoCl2(aq). a. You rinsed the cuvette with water before adding the sample of CoCl2 (aq).
b. You used a cuvette that had previously contained 0.80 M CoCl2 (aq).
c. The solution was incorrectly made and the concentration was 0.05 M.
d. The spectrophotometer was calibrated with 0.05 M CoCl2 (aq) solution instead of water.
e. You used a cuvette that was scratched on the sides.

The atom fluorine generally will become stable through the formation of an ionic chemical compound by accepting electron(s) from another atom. this process will fill its outer energy level of electrons.

Gusing the milligrams of ascorbic acid you entered above, the ratio of total sample volume to aliquot volume, and the total milligrams of the vitamin c tablet that you dissolved, calculate the mass of ascorbic acid in the vitamin c tablet for each trial. do this by scaling up to find the amount (mg) of ascorbic acid in your 250 ml flask. enter your calculated mass of ascorbic acid in the vitamin c tablet, for each trial. be sure to enter your calculated mass in the corresponding order that you entered your milligrams of ascorbic acid. the milligrams of ascorbic acid you entered for entry #1 previously should correspond to the mass of ascorbic acid that you enter for entry #1 here.
