Calculate the total amount of energy released if 20 g of given mass is completely converted into energy .

Explanation

To calculate the total amount of energy released when 20 grams of mass is completely converted into energy, we can use Einstein's mass-energy equivalence formula:

\[ E = mc^2 \]

where:
- \( E \) is the energy,
- \( m \) is the mass,
- \( c \) is the speed of light in a vacuum, approximately \( 3 \times 10^8 \) meters per second.
