Question
PLEASE I REALLY NEED HELP WITH THESE QUESTIONS!!!
Questions: 1. What are the units for density? 2. Define slope generally. Does slope have units in this case? If so, what are they? 3. What is the density of the object? 4. Why use a line rather than a single data point?

een slope and densitu in at CHEM 1151-Lab 2 Density Determination Objective: Use a graph to determine the density of an irregular object. Procedure: Use a balance to measure the mass of your assigned objects. Add some water to a graduated cylinder-measure the initial volume. Carefully add the object(s) to the cylinder (no splashing!)-measure the final volume. Add enough objects so that there is a change of at least one milliliter in the volume of water in the graduated cylinder. Measure the mass of a second object(s). Add to the cylinder-measure new volume. (Remember, add enough objects that the volume changes by at least 1 mL) Repeat same procedure for a total of 5 trials. Data collection/Results: Record data in the table provided below. Record your data using the correct number of significant figures based on the precision of your equipment. Table 1. Give the table a title that describes the data it contains. Total (cumulative) Volume of Total Volume of Volume of (cumulative) mass of objects adding object (g) water before water after water displaced (mL) 4.0mL 9.0 mL 11.DmL 15.0mL 19.0mb adding object (mL) पपल- Mass of (mL) objects (g) 9.140 8.980 9.430 9.363 9. 348 Trial 9.140 18.120 a1.550 40.0mL 44mL 49mı 5lmL 1 4amb 2 36.913 46.2l61 55 ml 59ML 4 5 Graph total mass of objects (y-axis) versus total volume of water displaced (x-axis). Determine the equation of the line if graphed data is linear, Y = mX + b where m is the slope of the line. Graphing checklist Graph fills Appropriate label/title for entire graph (e.g., Figure1. Speed of Object 5) least 2/3 of the notebook page Appropriate label for axis, including units Tick marks are clear and labels have appropriate significant figures Data points are of an appropriate size (large enough to see clearly) Reasonable number of data points (at least 5) Best fit line (or curve) is drawn and equation of line is placed on graph Equation is determined from the line rather than the data points (show pts used on graph)
