INSTRUMENTAL ANALYSIS AND SEPARATIONS HOMEWORK ASSIGNMENT 1 Safety, Sample Preparation, Measurement and Chemistry of Separation Summer 2011 Show all Work! 1) How many grams of NaOH do you need to add to make 1.00 liter of a 0.1 M NaOH? Dissolving NaOH in water is exothermic. Given this fact, explain how you would make an accurate 0.1 M solution? 2) How many mL of concentrated sulfuric acid are required to prepare 1.0 liter of a 0.1 M solution? (not all concentrated sulfuric acid is the same, and it is not 100%, find a reasonable value for concentrated sulfuric acid) 3) You want to find out the concentration of Furaneol in a sample of fresh pineapple. You extracted a sample of 10 g of fruit with 30 mL of ethyl acetate. You then concentrated the solvent extract by evaporation under a stream of nitrogen to 1.0 mL. After analysis by gas chromatography, you found that the concentration of Furaneol in your extract was 50 mg/L. What is the concentration of Furaneol in the fresh fruit? 4)
