Appendix determine the quantity

Use the following data and data from Appendix D in the textbook to determine the quantity of heat needed to convert 15.0g of solid mercury at -50.0∘C to liquid mercury at 25 ∘C. Specific heats: Hg(s), 24.3 Jmol−1K−1, Hg(l), 28.0 Jmol−1K−1. Melting point of Hg(s), -38.87 ∘C. Heat of fusion, 2.33 kJmol−1.
