W1-Ideal gases

Chemistry and Pharmacy: Key Concepts and Applications

• A three-year-old girl was abducted and murdered, and despite a suspect pleading guilty, no fingerprints were found in the car, which was processed four days after the abduction.
• Matter is classified into macroscopic states (solid, liquid, gas) and microscopic states (particle arrangement).
• Conversions, constants, and multiplication factors are essential in chemistry, including the mole road map.
• Gases and volatile agents are encountered in pharmacy, such as anesthetics, volatile drugs, and propellants for needle-free injection technologies.
• The ideal gas law describes the physical properties of gas, with the gas constant having a value of 8.314 J K-1 mol-1.
• Physical parameters like mass, volume, pressure, and temperature characterize the state of a sample, and SI units quantify each parameter.
• The ideal gas law is used to calculate pressure exerted by a gas, considering significant figures.
• The van der Waals equation of state modifies the ideal gas law to account for repulsion and attraction between gas molecules.
• Dalton's law states that the total pressure of a gas mixture is the sum of the pressures exerted by individual gases.
• Partial pressures of gas mixtures can be calculated using mole fractions and total pressure.
• The text recommends reading "Elements of Physical Chemistry" by P. Atkins and J. de Paula for further understanding of the topic.
• "Physicochemical Principles of Pharmacy" by A.T. Florence and D. Attwood, 4th Ed., is also suggested for additional context, available online through iCat.
