Unformatted text preview: the original sample, the mass of precipitate expected is 0.01 g. As a consequence, Score: 1/1 3. Gravimetry II In doing calculations concerning precipitation with dimethylglyoxime (DMG), you determine that if you use 1/4 of the original sample, the mass of precipitate expected is 1.25 g. As a consequence, Score: 1/1 4. Spectrophotometry You calculate the absorbance expected for a sample made by using 1/10th of the unknown sample, and it works out to 14.3. As a result: Score: 1/1 5. Interferences You know your sample is contaminated with MgCl 2 . As a result: Score: 1/1...
