(a)
To determine: An experimental procedure to obtain the reproducible ratio of the activity of pitchblende relative to that of pure uranium.
(b)
To determine: The possibility of using a device to measure the radioactivity quantitatively and the information to be used to identify the empirical formula of the given element.
(c)
To determine: The half life of the element in the sample and the possibility of different experimental constraints depending upon the different value of half-life.
(d)
To determine: The type of radiation emitted by the sample in the glow of Zinc sulphide and the device used for the quantitative measure of the amount of radioactivity in a sample.
