At what time will there be nuclei

Reference no: EM13693519

Here is the problem which I am confused on, please help me!

Problem: Nucleus A decays into the stable nucleus B with a half-life of 11.71 s. At t=0 s there are 1,384 A nuclei and no B nuclei. At what time will there be 546 B nuclei?

Please also explain, thank you in advance.
