Question

A certain chemical reaction experiences a 7.50 x 10-7 kilogram loss in mass. If this mass were to be totally converted to energy, what would be the magnitude of that energy? (1 J = 1 kg m2/s2)

1.20 x 1023 J

2.5 x 109 J

4.00 x 101 J

6.75 x 1010 J

Answer 1

Thanks @Kevin for all your help!

Answer 2

E = m x c^2
E = 7.50*10^(-7) * (3*10^8)^2
E = 67500000000

Answer 3
