How much energy is released if a sample loses 0.025 kg mass through
radioactive decay?

The amount of energy in radio active decay will be released 2.25 × [tex]10^{17}[/tex]J.
The process of radioactive decay is the loss of energy through radiation from an unstable atomic nucleus. The term "radioactive" refers to a substance that contains unstable nuclei.
Calculation of energy which released in radioactive decay.
Given data:
M = 0.025 kg
E = ?
Energy of the radioactive decay can be determined by using the formula:
E= m[tex]c^{2}[/tex]
where, E is energy , m is mass and c is speed of light.
Put the value of given data in above equation.
E = (0.025) ×(3×[tex]10^{8}[/tex])∧2J
E = 0.025 × 9 × [tex]10^{18}[/tex].J
E = 0.225 × [tex]10^{18}[/tex].J
E= 2.25 × [tex]10^{17}[/tex]J
Therefore, The amount of energy in radio active decay will be released 2.25 × [tex]10^{17}[/tex]J.
