What mass of copper has the same number of atoms as 26.98 g of aluminum? show your work for full credit!

a. convert the mass of aluminum to moles of aluminum. molar mass of aluminum (al) = 26.98 g/mol

b. convert the moles of aluminum to moles of copper. we are comparing the same amount (in moles) of aluminum and copper.

c. convert the moles of copper to mass of copper. molar mass of copper (cu) = 63.55 g/mol

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
