The standard molar heat of fusion of ice is 6020 J/mol. Calculate q, w, and (delta) E for melting 1.00 mol of ice at 0 deg. C and 1.00 atm pressure.

• Chemistry -

E = q+w
q = 6020 J/mol x 1 mol = ?
w = -pdV.
p is 101.325
Look up te density of ice and calculate the volume of a mol at zero C. Then calculate the volume of a mol of water at zero C. The differecne is dV. I found densities ice/H2O here.
