Chemistry was never a tough subject, ppl made it as tough. Without telling the actual definition of the some of important terms like weighted average, atomic mass unit, molecular weight etc. That was the time only few ppl had access to standard textbooks. Other than those ppl just reading whatever given in some non standard text books. Knowledge was just like a result of mind game and number game. Even after studying advanced calculus, linear algebra, numerical methods thermodynamics fluid mechanics structure of materials why chemistry was seems to be very tough subject? I couldn't understand? I couldn't digest this very fact?

why 1/12 of the mass of carbon-12 atoms considered as an atomic mass unit? where we can simply say the mass of a hydrogen atom or mass of proton/neutron is an atomic mass unit

[@drashtidoshi6009]

I have a doubt. When the mass is calculated as relative, then the units in numerator and denomintor get cancelled. The final answer should not contain a.m.u . Maybe you are using it wrong in the video.
