Abstract

The paper presents a way for students to use data from Rutherford's works (1908 - 1911) in order to determine one of the most precise values of Avogadro Constant available at the beginning of the century. A brief discussion of earlier and modern methods for the determination of this fundamental constant is followed by vast quotations from the works of Rutherford, Boltwood and Geiger. Then there are given a dozen of problems and questions for students about these classical experiments; they vary in complexity from rather simple to quite challenging. Additional information and hints are provided to help the students in solving the problems. The last part contains detailed answers and solutions to all problems. The article will be useful for students of general chemistry, radiochemistry and physical chemistry (kinetics).
