Can somebody help me calculate the energy released when 1g of uranium 235 undergoes fission reaction.Explain each step when the mass of particles are given as: 235U92 = 235.04u , 142Ba56 = 141.92u and 92Kr36 =91.92u. Im stuck on these calculations.Pls rescue me.

Of course, I can help you calculate the energy released during the fission reaction of 1g of uranium-235 (U-235) and guide you through each step. Let's break it down:

Step 1: Determine the number of moles of uranium-235.
To calculate the number of moles, we will use the following formula:

Number of moles = Mass of substance / Molar mass

The molar mass of uranium-235 (U-235) is given as 235.04u. To convert it to grams/mol, we need to multiply by the molar mass constant, which is approximately 1 g/mol.

Molar mass of U-235 = 235.04 g/mol

Number of moles of U-235 = 1 g / 235.04 g/mol

Step 2: Identify the products of the fission reaction.
The fission of uranium-235 typically results in the formation of two smaller nuclei. In this case, the products are barium-142 (Ba-142) and krypton-92 (Kr-92). The molar masses of these products are given as 141.92u and 91.92u, respectively.

Step 3: Calculate the total mass of the products.
To calculate the total mass of the products, we multiply the number of moles of uranium-235 from Step 1 by the molar mass of each product.

Mass of Ba-142 = Number of moles of U-235 * Molar mass of Ba-142

Mass of Kr-92 = Number of moles of U-235 * Molar mass of Kr-92

Step 4: Calculate the mass difference.
The mass difference is the difference between the initial mass (1g of U-235) and the total mass of the products (barium-142 and krypton-92).

Mass difference = Initial mass - Total mass of products

Step 5: Calculate the energy released using Einstein's mass-energy equation.
Einstein’s famous equation, E = mc², relates energy (E) to mass (m) through the speed of light constant (c). Since we have the mass difference from Step 4, we can calculate the energy released.

Energy released = Mass difference * c²

where c (speed of light) is approximately 3 x 10^8 m/s.

I hope this breakdown helps you understand the calculations.
