Weight of Neutron & Hydrogen Subscript 2

In summary, the weight of Tritium is 3.0160492 u, which is equivalent to 1.660538921(73)×10−27 kg. This information can be found on the Wikipedia articles for Tritium, Deuterium, and the unified atomic mass unit.

Hello all,
Does anyone know the weight of a neutron? Or, better yet, does anyone know offhand the weight of hydrogen subscript 2 (hydrogen isotope with two neutrons)?
Thanks!

Thanks!

To clarify notation:

H1 = ordinary hydrogen (no neutrons)
H2 = deuterium (one neutron)
H3 = tritium (two neutrons)

Oh, oops! Looks like I had a discrepancy between the subscript and neutron number. I did mean tritium, but I'd be curious to know the weight of deuterium (the real H2) as well.

Really, you should try to look this kind of information up yourself.
 

1. What is the weight of a neutron?

The weight of a neutron is approximately 1.675 x 10^-27 kilograms.

2. What is the weight of a hydrogen-2 atom (deuterium)?

The weight of a hydrogen-2 atom (deuterium) is approximately 2.014102 atomic mass units, which is equivalent to 3.343 x 10^-27 kilograms.

3. How does the weight of a neutron compare to the weight of a hydrogen-2 atom?

The weight of a neutron is slightly larger than the weight of a hydrogen-2 atom. This is because a hydrogen-2 atom contains one proton and one neutron, while a neutron is just one particle.

4. Why is the weight of a neutron difficult to measure?

The weight of a neutron is difficult to measure because it is a subatomic particle and cannot be directly observed. Scientists use various techniques, such as mass spectrometry, to indirectly calculate the weight of a neutron.

5. What is the significance of understanding the weight of a neutron and hydrogen-2 atom?

Understanding the weight of a neutron and hydrogen-2 atom is important in various fields of science, such as nuclear physics and astrophysics. It also has practical applications in industries such as energy production and medical imaging.
