Approximately how much energy is contained in 1 g of matter?

A. 3 * 1013 J

B. 9 * 1013 J

C. 3 * 1016 J

D. 9 * 1016 J

Option (B) is correct. Energy contained in one gram of matter=9 x 10¹³ J

Explanation:

mass = 1 g = 0.001 kg

c = velocity of light = 3 x 10⁸ m/s

The mass energy equivalence equation is given by

E = m C²

E = (0.001) (3 x 10⁸) ²

E=9 x 10¹³ J

Thus energy contained in one gram of matter=9 x 10¹³ J
