Explain decay to a mass of a half-life

Reference no: EM13716022

Question- How much time in years (assume a 365 day year for each year) would it take for a 2.849 g sample of 128Ba to decay to a mass of 1.136 g if it has a half-life of 2.0995e+5 s.

Please assists me to understand How to do fix this?
