1) 1 mol of P4(g) at 300°C, 0.01 atm
1 mol of As4(g) at 300°C, 0.01 atm2) 0.5 mol of N2(g) at 298 K, 20 L volume
0.5 mol of CH4(g) at 298 K, 20 L volumeI am not sure how to distinguish why in each problem how to know which one is more disordered?

standard entropies usually increase with an increase in molar mass, all other things being equal
P4…. S = 218 /mole @….
As4….S =314/mole @….(larger molar mass)
N2…S = 191.5/ mole @….(larger molar mass which increases S)
CH4…S= 186.3 @… ( has more atoms,which increases S),
this would have been hard to call
