Answer:
15.6 mg
Step-by-step explanation:
First 4 s- 500/2= 250 mg
After 8 s- 250/2= 125 mg
After 12 s- 125/2= 62.5 mg
After 16 s- 62.5/2= 31.25 mg
At 20 s- 31.25/2= 15.625 mg
The milligrams of a 500 mg sample will remain at 15.625 mg.
We have given that,
5.6 mg
Radon-219 has a half-life of about 4 s.
What is the sample?
A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger population.
After 20 s,
First 4 s- 500/2= 250 mg
After 8 s- 250/2= 125 mg
After 12 s- 125/2= 62.5 mg
After 16 s- 62.5/2= 31.25 mg
At 20 s- 31.25/2= 15.625 mg
Therefore, the milligrams of a 500 mg sample will remain 15.625 mg.
