delta E = delta m x c^2
2.5165E11 J = delta m x (3E8)^2
and delta m should come out in kg; BUT I don't see a choice there.
If a reaction yields 2.5165 × 10^8 kJ, then how much mass was lost? (User 3.00 x 108 m/s as the speed of light)
2.30 × 10^-3 kg
5.60 × 10^-3 kg
2.80 × 10^-12 kg
5.60 × 10^-12 kg
Please help.
