Infectious diseases are disorders caused by organisms — such as bacteria, viruses, fungi or parasites. Many organisms live in and on our bodies. They're normally harmless or even helpful, but under certain conditions, some organisms may cause disease. Some infectious diseases can be passed from person to person.
Answer:
3%
Explanation:
Substract the actual error from the final and multiply by 100
We have that
The average atomic mass round and to the second decimal place (0.01) is
A_m=126.90
From the question we are told
Find the average atomic mass round and to the second decimal place (0.01)
80% 127I, 17% 126I, 3% 128I
Generally the equation for the Average Mass is mathematically given as
Where
a1 = 127
b1 = 80%
a2 = 126
b2 = 17%
a3 = 128
b3 = 3%
Therefore
In conclusion
The average atomic mass round and to the second decimal place (0.01) is
A_m=126.90
