Heart of Fusion
« on: June 29, 2004, 12:38:46 PM »
My calculation for the heart of fusion in a kJ/mol if 10.0 g of solid chromium which absorbs 2.82 x 103 J of heat in melting came out at 34.3 kJ/mol. Can anyone double check this for me?

1 Mole of chromium weights 51.996 g.
Hence heat of fusion is (51.996/10.0)x2.82 kJ=14.7 kJ/mol (real value is 16.9)

Thanks, I caught what I did, I had an incorrect number for the mole.
