Question
What is the mass of hydrogen in terms of amu?
- 1.0020amu
- 1.0030amu
- 1.0060amu
- 1.0080amu
Hint:
To convert from gram to amu it is divided by 1.66056×10-24 g.
The correct answer is: 1.0080amu
The mass of a hydrogen atom is 1.6736×10-24 g. When converted in terms of amu, 1.6736×10-24 g should be divided by 1.66056×10-24 g.
(1.6736 
10-24) 
(1.66056 10-24) = 1.0078 amu 
1.008 amu
The mass of hydrogen in terms of amu is 1.008 amu.
