Homework Statement
What is the molar binding energy of uranium 235 nuclei?
Givem: The mass of 1 uranium nuecli is 235.0439u
Homework Equations
E=Δmc^2
The Attempt at a Solution
mass of nucleons: m=92P+143n=236.90814u
mass of nucleus: m=234.99343u
Δm=239.90814-234.99343u=1.9147u
Emolar=(1.9147u)(3x10^8m/s)^2(1.67x10^-27kg/u)
=2.8778x10^-10 J/nucleus (6.02x10^23 nuclei/mole)(1kJ/1000J)
=1.7324x10^11 kJ/mol
Is my answer correct? Also did I name the nucleons/nucleus correctly? I'm not sure if I should have called them what I called them since the nucleons are the nucleus technically.
