Given that mh = 1.007825 u, is the mass of a hydrogen atom 1h greater than, less than, or equal to 1/12 the mass of a 12c atom? select the correct answer and explanation.

Given that mH = 1.007825 u, is the mass of a hydrogen atom 1H greater than, less than, or equal to 1/12 the mass of a 12C atom? Select the correct answer.

A: 1/12 of the mass of a  12C atom is less than 1 u. Therefore, the mass of the hydrogen atom is less than 1/12 of the mass of a  12C atom.

B: 1/12 of the mass of a  12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is less than 1/12 of the mass of a  12C atom.

C: 1/12 of the mass of a  12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is greater than 1/12 of the mass of a  12C atom.

D: 1/12 of the mass of a  12C atom is greater than 1 u. Therefore, the mass of the hydrogen atom is greater than 1/12 of the mass of a  12C atom.

E: 1/12 of the mass of a  12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is equal to 1/12 of the mass of a  12C atom.

Correct option C i.e. 1/12 of the mass of a  12C atom is exactly 1 u. Therefore, the mass of the hydrogen atom is greater than 1/12 of the mass of a  12C atom.

Reason:

Carbon-12 has 6 protons, 6 neutrons and 6 electrons, while hydrogen has 1 proton and 1 electron. Due to this, 1/12 of the mass of a  12-C atom is exactly 1 u. and the mass of the hydrogen atom is greater than 1/12 of the mass of a 12-C atom.

it should be all of them because it asks if you included all of those in your answer
