If a 3.0 (pg) sample of curium-245 has a half-life of 8500 years, then the conclusion which can be drawn is the curium-245 sample will have a mass of about 1.5 pg after 8500 years

What is half life time?

Half life time is that time after which initial concentration of reactant becomes half of the initial.

Given that initial concentration of curium-245 = 3pg

After half life time concentration of curium-245 = 1.5pg

The curium-245 sample must have an age of at least 8500 years is wrong as given time is the half life time.
The curium-245 sample must have an age of less than 8500 years is wrong as given time is the half life time.
The curium-245 sample will have a mass of about 6.0 pg after 8500 years is alo wrong as left sample shold be half of the initial.

Hence, the curium-245 sample will have a mass of about 1.5 pg after 8500 years is the conclusion.
