1. The document reports experimental data from measurements of air mass, temperature, and humidity. It includes the raw data, averages, and standard deviations. 2. Uncertainty analyses were performed to determine the sources and magnitudes of uncertainty for the measurements. These include uncertainties from the balance, thermometers, humidity, pressure, volume coefficients, and resolution of instruments. 3. Combining the individual uncertainties according to propagation of error principles yielded the total expanded uncertainty in the measurements of air mass, temperatures, and a 50 mL volumetric flask calibration. The results were reported with nominal values and associated uncertainties.
