Calculate the change in entropy when one mole of metallic aluminum is heated at one bar pressure from an initial temperature of 25 °C to a final temperature of 750 °C. The molar heat capacities of solid and liquid aluminum at one bar pressure are 29.2 J mol K1 and 31.75 J mol K, respectively. The specific enthalpy of fusion of aluminum at its melting point (660.46 °C) is 396.57 J g1. The molar mass of aluminum is...

I thought when A has 2 mol and B has 1mol
mole fraction would be 2/3 for A and 1/3 for B
then the result is
delta S = -R (3N)*((2/3)ln(2/3) + (1/3)ln(1/3))
(and this was actually the answer of (4)!)
but the result is 3Rln(2).
