Question
Find the total number of iron atoms present in 224 amu iron.
- 5 atoms
- 4 atoms
- 6 atoms
- 7 atoms
Hint:
Atomic mass of iron is 55.845 amu.
The correct answer is: 4 atoms
Atomic mass of iron is 55.845 amu.
Number of iron atoms present in 224 amu iron = 224 
55.845 = 4
The total number of iron atoms present in 224 amu iron is 4.
