How much mass is equivalent to 1mj of energy? (1 mj=1*10^6 j) (the mass energy equivalence equation and speed of light are given below.) e=mc^2 c=3.0*10^8 m/s a. 3.3 * 10^-3 kg b. 1.1 * 10^-5 kg c.1.1 * 10^-11kg d.9.0*10^22kg

Energy - Mass equation is,
   E = mC²

E = Energy ( unit is J)
m = Mass of the particle ( Unit is kg)
C = Speed / velocity of light ( unit is m s⁻¹) = 3.0 x 10⁸ m s⁻¹

by rearranging the equation,
   m = E /C²
   m = 1 x 10⁶ J / (3 x 10⁸)² m² S⁻²
   m = 1.1 x 10⁻¹¹ kg

Hence the answer is "C".
