In 1 kilogram of pure water, the mass of hydrogen atoms is approximately 112 grams, or 0.112 kilograms. What is the energy equivalent of this mass in joules?
For the answer to this I got
E = mc^2.
Multiply m by c^2.
112 * (3 x 10^8)^2 m/sec.

1.008*10^19
Is this right?

do u mean energy equivalent 0.112 Kg

anonymous · Answer

I'm not sure - should I be using 0.112?

chmvijay · Answer

LOL it all depends on final unit and not what u use

anonymous · Answer

Well I believe that answer is in joules?

anonymous · Answer

Honestly I dont know when you work out the problem what do you get?

chmvijay · Answer

Joules = kg m^2/S^2
