Assume that when 1 kg of hydrogen undergoes fusion to helium, 6.4 × 10^14 j of energy is released. (a) calculate the amount of mass, in kilograms, converted to energy by the fusion of 0.75 kg of hydrogen. (b) what is the ratio of the converted mass to the original mass?

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
