How much energy is required to convert 18.0 g of ice at 0 °C to liquid water at 0 °C? (ΔHfus = 6.01 kJ/mol)
A.6.01 kJ
B.12.0 kJ
C.40.7 kJ
D.75.3 J
Explanation
Core Concept
18.0 g is exactly one mole, so melting needs 1.00 mol × 6.01 kJ/mol = 6.01 kJ, all used to loosen the lattice.
Correct Answer
A6.01 kJ
