In this lesson our instructor talks about tools in quantitative chemistry. First he discusses units of measurement, percent error, standard deviation, precisions, and accuracy. Then he talks about significant figures, uncertainty, identifying significant figures, using significant figures in calculation, and dimensional analysis. He ends the lesson with a summary and one helpful sample problem.
Dimensional analysis is the use of conversion factors to convert between different units, including the standard SI units of measurement.
Percent error is related to accuracy, while standard deviation is related to precision.
Significant figures are related to precision, and must be considered when performing calculations.
Significant figures are a relate to a measurement’s uncertainty.
