Answer : The energy released by the decay of 3 grams of 'Th' is
Explanation :
First we have to calculate the mass defect .
The balanced reaction is,
Mass defect = Sum of mass of product - sum of mass of reactants
conversion used :
Now we have to calculate the energy released.
The energy released is
Now we have to calculate the energy released by the decay of 3 grams of 'Th'.
As, 230 grams of Th release energy =
So, 3 grams of Th release energy =
Therefore, the energy released by the decay of 3 grams of 'Th' is
