42 43 44 45 Create and save a graph of mass ( y -axis) versus the volume ( x -axis) for aluminum. Click the graphing icon to create your graph. Click the box underneath the graph to show the trendline. It will automatically calculate your slope and intercept. The density equals the slope of the graph. 47 48 49 Experiment 4: Identify an Unknown Metal Lab Results 1 For each of the unknown metal measurements, use the data you collected during the experiment to record the quantities in the table below. Remember to pay attention to significant figures and record all masses and volumes with all the decimals provided by the lab.
Total volume of water plus metal (mL) 31.40 32.10 32.80 33.50 Total mass of metal in the cylinder (g) 10.000 15.000 20.000 25.000 12 13 14 15 Data Analysis 2 For each of the unknown metal measurements, use the data you collected during the experiment to calculate the quantities in the table below. Remember to pay attention to significant figures and record all masses and volumes with all the decimals provided by the lab. Please note that in this experiment the volume is your least precise measurement containing fewer significant figures than the mass. Therefore, the density can only be as precise as the volume. Net volume of metal (mL) Density of metal (g/mL) Average density of metal (g/mL) 15 16 Conclusions 1 Given that the density of glycerol is 1.261 g/mL, how much will 15.00 mL of glycerol weigh?
6 Given the density values for the metals in the table below, will the same volume of your unknown metal be lighter or heavier than copper?
Lighter 20 21 22 23 Why do you think it is important to record your data with all the decimals provided by the instruments even if they are zero? How will this help with data analysis?
