Comparison of density values determines whether an item will float or sink in water. For each of the values below, determine the density and determine whether it will FLOAT or SINK in water (density = 1.00 g/mL). (a) A wooden block with sides measuring 1.72 in and a mass of 11.9 g.
(b) A metal paperclip which displaces 0.293 mL of water when determining the volume by difference and weights 142 mg
(c) An apple which displaces 0.930 cups of water when determining the volume by difference and weighs 0.81 lb

Salicylic acid is a very important acid. it is used to synthesize the aspirin by treating with acetic anhydride. a 0.2015-g sample of salicylic acid was dissolved in a 100.00-ml volumetric flask, and the solution was diluted to the mark. a 10-ml aliquot of this solution was titrated with standard naoh (0.01130 + 0.2% n) to a phenolphthalein faint pink color end point at 19.81 ml. (a) (calculate the normality of the salicylic acid solution used in the titration. (b) assuming the salicylic acid is pure, what is the equivalent weight of the salicylic acid? practice problems for the final exam (continued) (c) (calculate the inherent error in the determination of the equivalent weight you calculated in part (b). use the following absolute errors in the equipment /glassware when calculating the inherent error. 5.00-ml pipet: + 0.02 ml 100-ml volumetric flask: + 0.08 ml analytical balance: + 0.2 mg 25-ml buret: + 0.03 ml
