# Nuclear chemistry help please!?

The answer is supposed to be 2.39*10^8 kJ but I’m not sure how to set this up. Please try to be detailed instead of giving one word hints. Thank you in advance.

There are a couple of different ways to do this

From the Bal. eq. use MOLAR MASS and find the difference in mass on the product and reactant sides. This will the the change in mass which changes into energy according to Einstein's equation .. E = mc^2

calculate the energy .. c is the speed of light

... last ... this is for a mole Li .. 6.016 g. So divide the Energy answer by 6.016 to find the energy released by 1 g
