Question

Water has a heat of fusion of 6.01 kJ/mol. An iceberg in the Atlantic Ocean near Newfoundland contains 1.27 x 107 mol of water. How much thermal energy does it absorb as it melts? Answer using appropriate significant digits. Please record your work in your notes for future reference.

Answer 1

7.63×10⁷ kJ

Step-by-step explanation:

From the question given above, the following data were obtained:

Heat of fusion (Hբ) = 6.01 kJ/mol

Number of mole of water (n) = 1.27×10⁷ moles

Heat (Q) absorbed =?

The thermal energy absorbed can be obtained as follow:

Q = n•Hբ

Q = 1.27×10⁷ × 6.01

Q = 7.63×10⁷ kJ

Thus, 7.63×10⁷ kJ of thermal energy is absorbed.
