Answer:
5 half-lives
Explanation:
Original value Half-lives
1 0
1/2 1
1/4 2
1/8 3
1/16 4
1/32 5
Answer:
This means it takes 5 half-lives after 1/32 of the original strength is found
Explanation:
Step 1: Data given
1/32 of the original strenght will remain after X time
Step 2: Calculate Number of half-life times
Let x be the number of half-lives.
For 1/32 left
2^-x = 1/32
x = 5
This means it takes 5 half-lives after 1/32 of the original sample is found
We can control this like:
After 1 half- life half of the sample is left = 1/2 of the original strength is found
After 2 half-lives, there will remain 1/4 of the original strength is found
After 3 half-lives, there will remain 1/8 of the original strength is found
After 4 half-lives, there will remain 1/16 of the original strength is found
After 5 half-lives,there will remain 1/32 of the original strength is found
