### Analysis of the Options

1. **Molarity**: This is a measure of concentration in moles of solute per liter of solution (mol/L). It is commonly used in chemistry but specifically relates to solutions.

2. **Percent**: This typically refers to a ratio of the amount of solute relative to the total amount of solution, expressed as a fraction of 100. It is a general measure of concentration but might not specifically relate to dissolved gases.

3. **Pressure**: This refers to the force exerted by gas molecules when they collide with the walls of their container. In terms of dissolved gases, pressure can influence solubility but is not a direct measure of concentration.

4. **PSI**: This stands for pounds per square inch, a unit of pressure measurement. Like "pressure," it relates more to the measurement of force rather than concentration.

### Conclusion

The most appropriate choice for expressing the concentration of dissolved gases is **molarity**, as it provides a quantitative measure of how much of a gas is dissolved in a specific volume of solvent.
