If a radioactive decay produced 2. 05 × 1011 j of energy, how much mass was lost in the reaction?

Sagot :

The mass lost in the reaction is 0.227 × [tex]10^{-5}[/tex] Kg

The energy that is released during a nuclear reaction can be related to the mass lost using the Einstein equation.

E = m[tex]c^{2}[/tex] by Einstein demonstrates that matter and energy are only two different manifestations of the same thing. It also demonstrates how much energy (E) can fit into a relatively small mass (m) of matter. Nuclear processes convert matter into energy, yet the combined amount of mass and energy remains constant.

Given that;

E = Δ[tex]mc^{2}[/tex]

Δm = [tex]\frac{ E}{c^{2} }[/tex]

Δm =  2. 05 × 10^11  J/( 3 × 10^8)^2

Δm = 0.227 × [tex]10^{-5}[/tex] Kg
