Short Answer

Calculate the disintegration energy Q for the fission of C52r into two equal fragments. The masses you will need are

role="math" localid="1661753124790" C52r 51.94051 M26g 25.98259u

The disintegrated energy is -23 MeV.

See the step by step solution

Step by Step Solution

Step 1: Given data

The mass of C52r, mcr=51.94051u

The mass of M26g, mMg=25.98259u

Step 2: Determine the formula to calculate the disintegrated energy.

The expression to calculate the disintegrated energy is given as follows.

Q=mc2Q=(mCr2mMg)c2 ...(i)

Step 3: Calculate the value of disintegrated energy.

Consider the fission reaction as given follow.

C52r M26g+M26g

Calculate the disintegrated energy.

Substitute 51.94051u for mCr , 25.98259u for MMg and 931.5 MeV/u for c2 into equation (i).

Q=51.9405u-2×25.98259u931.5 MeV/uQ=-0.02467×931.5 MeVQ=-23 MeV

Hence the disintegrated energy is -23 MeV.
