Question

Just one question...Please? Just check ONE answer. I need to know if I got it right.

If a reaction yields 2.5165 × 10^8 kJ, then how much mass was lost?
2.300 × 10^3 kg

5.600 × 10^3 kg

2.800 × 10^6 kg

--> 5.600 × 10^6 kg

Answer 1

Is that 108 or 10^8? But you just divide by c^2

Answer 2

My answer was wrong anyway so it doesn't really matter anymore. It was 2.800 x 10^6 kg not 5.6 x 10^6 kg. :(
