(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Nuclear energy changes are significantly greater than chemical changes. The detonation of 1.00 g of the explosive trinitrotoluene (TNT) releases 2.760 kJ. How many grams of TNT would be needed to match the energy released by one gram of U-235?

( 1 gram of U-235 contains 2.56*10^21 nuclei)

2. Relevant equations

3. The attempt at a solution

Basically, it is a continuation of the previous question in which i found that the amount of energy released in fission of U-235 nucleus is 2.82*10^-11J.

what i did was multiply (2.82*10^-11)(2.56*10^21)= 7.22*10^7kJ, i then divided that amount

7.22*10^7kJ/2.760kJ= 2.6*10^7 ( although the units are not in grams , what am i doing wrong)
