Calculate the Amount of Enthalpy Required to Heat 25 $\Delta$ H_fus = 9

question 71

Short Answer

Calculate the amount of enthalpy required to heat 25.0 g of solid benzene (C₆H₆)at -10°C to liquid benzene at 20.0°C.Thermodynamic data for benzene: specific heat of solid benzene = 1.52 J/g·°C; specific heat of liquid benzene = 1.73 J/g·°C; melting point = 5.5°C; $\Delta$ H_fus = 9.9 kJ/mol.
