Calculating Atomic Mass: Solving for Pi Meson's Mass in AMU

Click For Summary
To convert the mass of a pi meson, which is 139 MeV/c^2, into atomic mass units (amu), one must use the conversion factor of 931.5 MeV/c^2 per amu. This means that the mass of the pi meson in amu is calculated by dividing 139 MeV/c^2 by 931.5 MeV/c^2. The result is approximately 0.149 amu. The discussion clarifies that amu is defined as 1/12 the mass of a carbon-12 atom, correcting earlier misconceptions about its relation to the mass of a proton. Understanding these conversions is essential for accurate calculations in particle physics.

A pi meson has mass of 139MeV/c^2. what is this in atomic mass?

HOw do i solve for this? what steps do I need to do, any examples you can give to help me with to solve?
Dx :wink:

Dx,

I made a mistake. The amu is not the mass of one proton, it is 1/12 the mass of a C12 atom.
 
I believe 1 amu is something like 812 MeV/c^2..bah...i don't know the exact number, its something in the 800's

EDIT: Its 931.5 MeV/c^2 for each amu
 
Thanks you guys are the bomb! :wink:
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
