Answer:
So, you're dealing with a sample of cobalt-60. You know that cobalt-60 has a nuclear half-life of
5.30
years, and are interested in finding how many grams of the sample would remain after
1.00
year and
10.0
years, respectively.
A radioactive isotope's half-life tells you how much time is needed for an initial sample to be halved.
If you start with an initial sample
A
0
, then you can say that you will be left with
A
0
2
→
after one half-life passes;
A
0
2
⋅
1
2
=
A
0
4
→
after two half-lives pass;
A
0
4
⋅
1
2
=
A
0
8
→
after three half-lives pass;
A
0
8
⋅
1
2
=
A
0
16
→
after four half-lives pass;

Answer:
Precentage error = 7.23%
Explanation:
The precentage error formula is the useful method for determining precision of your experimental result
It can be calculated using :
So we get percentage error = 7.23%
Precision means how close the experimental value to the true value or theoretical value
If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment
If the percentage error is zero it means the experiment is perfectly done without inaccuracy
Answer: TOOOOOOOOOOOOOOOOOOOO
