Interpretation:
The mass of P-32,S-33 and Fe-59 percent in the original solution has to be given.
Concept Introduction:
Radioactive Law:
The radioactive lawstates that the probability per unit time that a nucleus will decay is a constant independent of time. This constant is called the decay constant and is denoted by
Where N is the number of radioactive nuclei remaining after time t
N0 is the number of radioactive nuclei in initial time.
k is the decay constant.
t is the time required to decay.

- A sample of rock was found to contain 8.23 mg of rubidium-87 and 0.47 mg of strontium-87.. (a) Calculate the age of the rock if the half-life of the decay of rubidium by emission is 4.71010 y. (b) If some S3887r was initially present in the rock, would the rock be younger, older, or the same age as the age calculated in (a)? Explain your answer.arrow_forwardDefine the term half-life and illustrate it with an example.arrow_forwardWrite a nuclear reaction for each step in the formation of P82208b from T90228h, which proceeds by a series of decay reactions involving the step-wise emission of a, ,,,,,, particles, in that order.arrow_forward
