The molar heats of fusion and vaporization for silver are 11.3 kJ/mol and 250. kJ/mol, respectively. Silver's normal melting point is 962°C, and its normal boiling point is 2212°C. What quantity of heat is required to melt 13.0 g of silver at 962°C?
CHEMISTRY..please help..thanks - bobpursley, Tuesday, November 2, 2010 at 8:24pm
heat to melt= mass*latentheatfusion
= 13.0g*11.3kJ/mol *1mol/xxxgrams
so look up xxxg as the molemass of Ag
