Certain parts of the world don't have enough fresh drinking water. one possible solution is to tow icebergs from antarctica and melt them as needed. if 6.10 ✕ 1011 kj of energy were needed to melt an iceberg, how much did the iceberg weigh? the enthalpy of fusion (melting or freezing) for ice is 6.01 kj/mol, and 1 metric ton = 1,000 kg. metric tons
