Question

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

Answer 1

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

Step-by-step 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
