Palladium-103 (Pd-103) has a half-life of 17 days. Its molar mass is 0.10291 kg/mol.
1) What is the decay constant of Pd-103?
2) What is the initial activity of a 750-gram sample of Pd-103?
3) What is the activity of the sample after 51 days?
4) After how many days will the activity decrease to 1/20th of the initial activity?
