How much of a radioactive kind of calcium will be left after 10 days if the half-life is 5 days

Mathematics
1 answer:
Sophie [7]4 years ago

Answer: 16 g

Step-by-step explanation:

We can solve this with the Radioactive Half Life Formula:

A=A_{o}.2^{\frac{-t}{h}}    

Where:

A is the final amount of radioactive calcium

A_{o}=64 g is the initial amount of radioactive calcium

t=10 days is the time elapsed

h=5 days is the half life of radioactive calcium

Solving with the given data:

A=(64 g)2^{\frac{-10 days}{5 days}}    

A=16 g  This is the amount of radioactive calcium left
