Atomic weights are not provided, but please use rounded-off values to the nearest whole number.(examples: 24.305, use "24"; 107.8682, use "108"; 1.00784, use "1"; 15.999, use "16") Add trailing zeros to complete your answer to the 3rd decimal place, if necessary. (examples: if your answer is "62.7", write it as 62.700; if your answer is "37.12", write it as 37.120if your answer is "123", write it as 123.000) 1. A 3.50-gram sample of Streptomycin powder was tested for its water content. If the water equivalence factor of the KF reagent was 4.6, what is the percentage water content of the sample if 9.2 ml of the KF reagent was used? 2. An analyst accurately weighed 5.351 grams of sample for ash-insoluble content using the dry method. The weight of the crucible containing the ash was 40.722 grams. If the sample was said to have 2.150% of insoluble ash, what is the weight of the tared crucible?

A 1.2-gram sample of lanolin was treated with Wij’s solution and excess potassium iodide solution. The liberated iodine reacted with 30 ml of 0.1 N sodium thiosulfate solution. If the iodine value was determined as 12.69, what is the volume used in blank titration? 2. A 500mg oil sample is taken from a conical flask and is dissolved in 50mL distilled alcohol. An indicator is added and is then titrated against 0.112N KOH until a slight pink color appears. It took 17.6mL of the titrant to reach the endpoint. What is the sample’s Acid Value?
