Rubidium-86 (86Rb) undergoes beta decay. A 9.52 x 10^−5 mol sample of 86Rb emits 8.87
x 10^16 beta particles in one hour. Calculate the half-life (in hours) for 86Rb

First show your own attempt.
What are the formulas for calculation of half life time.
Hint how many atoms in the sample and how many atoms represent the ß-particles.
