A certain chemical reaction experiences a 7.50 x 10-7 kilogram loss in mass. If this mass were to be totally converted to energy, what would be the magnitude of that energy.

E=6.75*10¹⁰J

Explanation:

Given data

Mass (m) = 7.50*10⁻⁷kg

To find

Energy (E) = ?

Solution

From Albert Einstein's theory of special relativity

E = mc² ... eq (1)

Where

E is energy

m is mass

c is speed of light which 3.0*10⁸m/s

put values in eq (1) we get

E = (7.50*10⁻⁷kg) * (3.0*10⁸m/s) ²

E=6.75*10¹⁰J
