Let's analyze each question one at a time:
**Question 7:** Which of the following will have the largest absolute molar entropy?
- 0.5 moles of water vapor
- one mole of water vapor
- one mole of liquid water
- 0.5 moles of liquid water
**Answer:** One mole of water vapor will have the largest absolute molar entropy. Molar entropy generally increases with the amount of substance (moles) and is higher in the gaseous state compared to the liquid state. Since one mole of water vapor has more disorder and more microstates than the other options, it has the highest absolute molar entropy.

**Question 8:** Which of the following will have the largest absolute entropy?
- one mole of H2O2 liquid and one mole of H2O liquid
- two moles of H2O2 vapor
- two moles of H2O vapor
- one mole of H2O2 vapor and one mole of H2O vapor
**Answer:** Two moles of H2O vapor will have the largest absolute entropy. Gases generally have higher entropy than liquids due to their greater degree of freedom for molecular motion. Additionally, the two moles of H2O vapor represent more material in a gaseous state than the other combinations.

**Question 9:** Which of the following will have the largest absolute entropy?
- A mole of polypeptide that has a mass of 600 g/mole
- A mole of a protein that has a mass of 100,000 g/mole
- A mole of an amino acid that has a mass of 180 g/mole
**Answer:** A mole of a protein that has a mass of 100,000 g/mole is likely to have the largest absolute entropy. Larger macromolecules (like a protein) generally have a greater number of ways to arrange themselves (more microstates) compared to smaller molecules (like an amino acid or polypeptide). Hence, the larger protein should have the highest entropy compared to the others listed.

In summary:
1. One mole of water vapor (largest molar entropy).
2. Two moles of H2O vapor (largest absolute entropy).
3. A mole of a protein that has a mass of 100,000 g/mole (largest absolute entropy).
