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

Weight of the iceberg is metric ton

Explanation:

Molar mass of = 18 g

So, 6.01 kJ of heat energy is needed to melt 18 g of ice

Hence, kJ of heat energy is needed to melt of ice or g of ice

Now, = 1 metric ton

So, g = 1 metric ton   ( 1 kg = 1000 g)

Hence, g = metric ton = metric ton

So, weight of the iceberg is metric ton

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
