A.
It takes 4 hh 39 minmin for a2.00-mgmg sample of radium-230 to decay to 0.25 mgmg.
Part A
What is the half-life of radium-230?
B. How much time is required for a 5.85 mgmg sampleof 51Cr51Cr to decay to 0.850 mgmg if it has ahalf-life of 27.8 days?
C.
The cloth shroud from around a mummy is found to havea 14C14C activity of 10.3 disintegrations per minute pergram of carbon as compared with living organisms that undergo 16.3disintegrations per minute per gram of carbon.
Part C
From the half-life for 14C decay, 5715 yr, calculatethe age of the shroud.
