please help me with tyese questions

1. From the data below, calculate the total heat (in J) needed to convert 0.333mol of gaseous ethanol at 300.C and 1.00atm to liquid ethanol at 25.0C and 1.00atm. Boiling point of ethanol at 1.00atm:78.5C cgas=1.43J/gC Hvap=40.5kJ/molcliquid=2.45J/gC Show your calculation setup clearly, and pay attention to units and sig figs in the answer. 2. Assume three sig figs throughout this problem. Methane (CH4) has a bp of 164C at 1atm, and a vapor pressure of 42.8atm at 100C, What is the heat of vaporization of CH4 ? Show your calculation setup clearly, and pay attention to units and sig figs in the
