What is the energy equivalent of 0.026 kg?

7.8 x 10⁶ J

Explanation:

using the Mass-Energy equivalence formula,

i. e E = mc²

where

E = energy

m = mass = given as 0.026 kg

c = speed of light = which we will assume to be 3 x 10⁸ m/s

substituting the above into the formula

E = mc²

= 0.026 x (3 x 10⁸) ²

= 0.026 x (9 x 10¹⁶)

= 2.34 x 10¹⁵ J
