\u25a0 Measurement method of density using a glimpsed pycnometer type I type (Refer to JIS K2249) 1) The mass (M0) of the picknometer is applied to the 0.1m digit. 2) With the picknometer standing up, the sample set to 15 \u00b0 C is filled with the appropriate scale of the fine tube from one end of the hook to the appropriate scale of the fine tube. 3) Soak the picknometer with a sample in a constant temperature tank at 15 \u00b1 0.05 \u00b0 C. 4) When the scale is constant, read the liquid surface of the two -bodies until 1\/2 of the small scale, and record the total. 5) Take out the picknometer from the constant temperature aquarium, rinse the outside, wipe it with a purifier, dries it, and apply the mass (M \u25bc 15 \u25bd) to 0.1m. 6) Calibric line diagram * (1) In search of the water mass (M \u25bc 15 \u25bd) corresponding to the total value of the scan of a picknometer, this is the mass of the volume of the volume of the volume at 15 \u00b0 C. Calculate the density of the sample from the following equation. d \u25bc 15 \u25bd = {(m \u25bc 15 \u25bd -m \u25bc 0 \u25bd) \u00d7 D \u25b2 15 \u25b3 W\/m \u25bc 15 \u25bd}+CD \u25bc 15 \u25bd \u25bd M \u25bc 15 \u25bd: Mass bottle, bottle and cap mass (g) m \u25bc 0 \u25bd: Mass (G) D \u25b2 15 \u25b3 W: Water density (15 \u00b0 C) 0.99910g\/cm \u25b2 3 \u25b3) m \u25bc 15 \u25bd: Mass of water obtained from the calibration line map (g) C: Correction value for buoyancy of air (G\/CM \u25b2 3 \u25b3) (JIS K2249 Table See 20) * (1): The calibration diagram is created when proofreading a picknometer.
