REPORT SHEET Date 09/12/2023 Measurement Name Partner Zakia Swanson Include with this report sheet the data sheet and both graphs. 1. Results: The density of water will be the slope from the appropriate graph. Reread the “Data Analysis” section if necessary for complete understanding. Density of water using the graduated cylinder (include proper units): Density of water using the buret (include proper units): 2. Which measuring device would you use if you needed to know the volume of a liquid very precisely? Why? A graduated cylinder is the most precise for measuring the volume of a liquid because of the small tick marks in between the big numbers, which provide scientists and ordinary people with an accurate yet precise reading of the volume of liquid thy are looking for. 3. Using the data from the Trials with Graduated Cylinder (Trial 1) divide the mass recorded by the volume of H2O. Show the work and be sure to use units and the appropriate significant figures. What is the answer? Explain why this is not the density of water! 4. From the equation: m = DV the intercept value appears to be zero, which makes sense because if there is no volume, the mass of the liquid will be zero. Look at graph 2 (Buret) and determine the "y intercept" both visually and mathematically. Use proper units for both values listed. Visual intercept (if possible; if not possible put Not Possible on line) Mathematical intercept: (from the equation of the line) (You can consult the lab manual for information about the intercept or check with the instructor) Why is this value not zero and what does this value represent in the real, physical world?
