Question

What is the binding energy (KJ/mole) of radium-226, whose mass is 226.0254 g/mole .

NOTE: The answer should be a positive number.





Enter a numeric answer only do not include units in your answer.

Answer 1

2.286 x 10^11 kJ/mol

Answer 2

Use the equation E = m c^2 Phosphorus 31 has 15 protons and sixteen neutrons. 15 protons*a million.00783 g/mol = 15.11745 sixteen neutrons*a million.00867 g/mol = sixteen.13872 entire mass = 31.25617 g/mol Subtract that from 30.97376 Multiply by the fee of light (2.99e8) squared. Divide by one thousand to transform g to kg, and by one thousand lower back to transform J to kJ. To calculate the binding capacity in line with nucleon, basically divide the capacity you got from section a million by the completed form of nucleons (protons + neutrons = 31) do no longer ignore to respond to section a million as a great quantity! :)
