For each reagent listed below indicate if it can be used to separate the ions. Type "Y" for yes or "N" for no. If the reagent CAN be used to separate the ions, give the formula of the precipitate. If it cannot, type "No" Submit Answer Y or N Reagent Formula of Precipitate if YES 1. KOH 2. 3. Retry Entire Group Na₂S04 NaCl 8 more group attempts remaining

Consider the following data that was collected for a protein that contain 0.76 % tryptophan amino acids by weight (Molecular weight of tryptophan amino acids is 204 g/mol). Absorbance Concentration (mg/L) 0.0250 0.100 0.150 0.226 0.259 0.400 0.600 0.964 1.14 1.78 1.45 2.35 1.78 2.87 How many mg of the protein present in 1.00 L solution that shows an absorbance of 1.20?
