The amount of dry ice that can be made from a tank of carbon dioxide gas that has a volume of 6.0 cubic feet with a gauge pressure of 2.00 × 10 3 pounds per square inch at 22 ° C is to be determined. Concept Introduction: The ideal gas equation is an improvised form of combined gas law equation. It explains that the product of pressure and volume of a gas when divided with the temperature of the gas, makes the resultant value proportional to the amount /moles of gas.

elow are experimentally determined van Deemter plots of column efficiency, H, vs. flow rate. H is a quantitative measurement of band broadening. The left plot is for a liquid chromatography application and the night is for gas chromatography. Compare and contrast these two plots in terms of the three band broadening mechanisms presented in this activity. How are they similar? How do they differ?
