Equilibrium : CalcKp (2 Variations)
In one experiment chemists studied the formation of phosgene, COCl2, by mixing {y} atm of carbon monoxide and {z} atm of Cl2 in a reaction vessel at 700K. After the system reached equilibrium, the total pressure was {x} atm. Calculate Kp for the reaction.

Hint: Remember that the total pressure is the sum of all the partial pressures.

The Penny Experiment Revisited: An Illustration of Significant Figures, Accuracy, Precision, and Data Analysis  Joseph Bularzik
In this general chemistry laboratory the densities of pennies are measured by weighing them and using two different methods to measure their volumes. The average and standard deviation calculated for the resulting densities demonstrate that one measurement method is more accurate while the other is more precise.

Improving Conceptions in Analytical Chemistry: ci Vi = cf Vf  Margarita Rodríguez-López and Arnaldo Carrasquillo Jr.
A common misconception related to analytical chemistry, which may be generalized as the failure to recognize and to account analytically for changes in substance density, is discussed. A cautionary example is made through the use of mass-based units of composition during volumetric dilution. The correct application of the volumetric dilution equation ci Vi = cf Vf is discussed. A quantitative description of the systematic error introduced by incorrect use of the volumetric dilution equation is also specified.

Cross-Proportions: A Conceptual Method for Developing Quantitative Problem-Solving Skills  Elzbieta Cook and Robert L. Cook
This paper focuses attention on the cross-proportion (C-P) method of mathematical problem solving, which was once widely used in chemical calculations. We propose that this method regain currency as an alternative to the dimensional analysis (DA) method, particularly in lower-level chemistry courses. In recent years, the DA method has emerged as the only problem solving mechanism offered to high-school and general chemistry students in contemporary textbooks, replacing more conceptual methods, C-P included.
