The Energy Released by a Certain Reaction Is Enough to Totally

Short Answer

The energy released by a certain reaction is enough to totally evaporate $125 \mathrm {~kg}$ of water at its boiling point. How much mass was lost during this reaction? $\left( L _ { F } = 334,000 \mathrm {~J} / \mathrm { kg } \right.$ for water, $c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s }$ )
