7. how much thermal energy is absorbed when 10.0 g of ice at 0.0 degrees c changes phase to liquid water at 0.0 degrees c? the molar mass, m, of water is 18.02 g/mol and the theoretical heat of fusion, hfus, of water is 6.01 kj/mol

3.34 kJ

Explanation:

FIrst of all, we need to calculate the number of moles corresponding to 10.0g of ice. This is given by

where

is the molar mas

m = 10.0 g is the mass

Substituting

Now we know that the heat of fusion is

so the thermal energy needed to fuse the ice is

which statement about this sum is true? −245+2.7

i need the answer to this too but idk it ; -;
