1: Measurements and Problem-Solving

( \newcommand{\kernel}{\mathrm{null}\,}\)

  • 1.1: Measurements Matter
    Measurements in chemistry are reported with a variety of units. The standard units for various measurements are discussed along with the modifying prefixes for these units.
  • 1.2: Significant Figures
    Significant figures are important in reporting values because the numbers used in chemistry are based on measurements.  The precision of a measurement should not be under- or over-reported through the use of the wrong number of significant figures.
  • 1.3: Scientific Dimensional Analysis
    Dimensional analysis (also called factor label method or unit analysis) is used to convert from one set of units to another. This method uses relationships or conversion factors between different sets of units. While the terms are frequently used interchangeably, conversion factors and relationships are different.
  • 1.4: Percentages
    Percentages are used in a variety of ways in healthcare including concentrations of solutions, medication dosages, and reporting changes to measured values for patients over time.
  • 1.5: Measurements and Problem-Solving (Exercises)
    These are homework exercises to accompany Chapter 1 of the University of Kentucky's LibreText for CHE 103 - Chemistry for Allied Health. Solutions are available below the questions.
