The mass is
Explanation:
The equation for the radioactive decay is
The initial mass is
The half life is
The radioactive constant is
Therefore,
The time is
Therefore,
I get
Explanation:
From here, If
The half-life of this substance is
So, after
Multiplying that by the original mass, there will only be
Therefore, there will only be
