Answer
See explanation below.
Work Step by Step
1
P4(g) has higher molar entropy than P2(g) because more vibrational motion is possible in P4 as compared to P2
2
HNO3(aq) has higher molar entropy than HNO3(l) because more freedom of motion for HNO3 in aqueous phase
3
CuSO4(s) has lower entropy than CuSO4.5H2O(s) because heavier atom has more entropy
