Document Summary
The purpose of this lab was to become familiar with common laboratory equipment, techniques, and data collection, and to understand the uncertainties of measurements, significant figures, and propagation of error. The procedure of this lab can be found on pages 24-25 in general chemistry che110l. Calculations: density of water (not interpolated) = 0. 997770g/ml, volume of pycnometer: mass of water density of water= 0. 997770g/ml= 25. 992ml: mass of water not occupied by the metal: Mass of water= (mass of pycnometer+water+metal) [(mass of pycnometer) + (mass of metal)] =57. 778-21. 602-12. 416= 23. 76g: volume of water not occupied by the metal: Volume= mass of water not occupied by the metal. 2. 179g/ml= 5. 698g/ml mass of metal volume of metal= The purpose of this lab was to become familiar with common laboratory equipment, techniques, and data collection and to understand the uncertainties of measurements, significant figures, and propagation of error.
