You are performing an experiment that uses 114ag. 113ag is radioactive, decays by beta-- emission and has a half-life of 21 minutes. it requires 4.2 hours to ship the material from the warehouse to your laboratory. how many grams should you order if the experiment requires that you have 0.0575 grams to begin the experiment?
Answers: 1
= 21 min
![\log[N]=\log[N_o]-\frac{\lambda t}{2.303}](/tpl/images/0019/8651/186bc.png)
![\log[0.0575 g]=\log[N_o]-\frac{0.033 min^{-1}\times 252 min}{2.303}](/tpl/images/0019/8651/dfaf0.png)
