🤓 Based on our data, we think this question is relevant for Professor Roychowdhury's class at RUTGERS.
Recall that half-life is the time needed for the amount of a reactant to decrease by 50% or one-half.
The half-life of a first-order reaction is given by:
t1/2 = half-life
k = decay constant
The bromine-82 nucleus has a half-life of 1.0 X 10 3 min. If you wanted 1.0 g 82Br and the delivery time was 3.0 days, what mass of NaBr should you order (assuming all of the Br in the NaBr was 82Br)?
