what is the entropy change that occurs when 500g of water ice melts at 0 degrees celsius and 1 atm. the heat of fusin for water ice under these conditions is 6.01 Kj/mol.

Answer 1

delta Hfus = Tfus x delta Sfus
Convert 500 g H2O to moles and convert that to kJ, substitute into the above equation and calculate delta Sfusion. Don't forget T must be in Kelvin
