For your given alcoholic beverage, state which alcoholic beverage you were given and the density of the beverage. 2. You determined the density of 0.5%, 1.2%, 7% and 22.9% alcohol. Given this information, in what range of alcohol percentage does your given beverage lie? 6 D. Focus CE English (United States) W A EN o BI search r3. Alcohol percentage and density show a linear relationship. In Excel, use your table of alcohol percentages and densities to construct a graph showing this linear relationship. Insert a copy of the plot generated and give its mathematical formula (y=mx+b). 4. Given the plot you generated and its formula in question 3, predict the alcohol percentage for your given alcoholic beverage. Show all calculations involved. References D Focus sh (United States) r5. Based on the volume needed of 70% alcohol needed to make 100ml of 22.9% alcohol, click and add the appropriate glassware to the workbench. Using the tab in the prompt to “Precise”, enter your calculated volume into the textbox to transfer the 70% alcohol to the glassware. 5. Click on “Volumetric Flask" under the "Glassware" Tab. Choose the 100ml volumetric flask. Transfer the 70% alcohol into this flask. Click on "Distilled Water" under the “Solution" tab. Using the appropriate glassware, transfer enough water to the 100ml volumetric flask to create 100ml of 22.9% alcohol. Drag and drop the beaker onto the scale. Record the mass of the beaker. 3. bTransfer 100ml of 22.9% alcohol to the beaker. Record the mass of the 22.9% alcohol and beaker. Calculate the density of 22.9% alcohol. 0. Right click to clear your workbench and repeat the steps to make 100ml of 0.5%, 1.2%, and 7% alcohol respectively to determine their densities. 1. Please record all your data in the table provided below. D Focus rU Glassware" tab. 5. Click on the 250 mL beaker to add it to the workbench. 6. Click on the "Scale" under the "Tools" tab to add it to the workbench. 7. Click the 10ml graduated cylinder in the "Glassware" tab and add it to the workbench. 8. Drag and drop the alcoholic beverage over the graduated cylinder. You should see a prompt for pouring. Change the tab in the prompt to "Precise". Enter “10” into the textbox and click “pour". 9. Drag and drop the beaker onto the scale. Record the mass of the beaker. 10. Drag and drop the full graduated cylinder onto the beaker sitting on the scale. You should still be under the 'Sig Fig" tab. Enter 10.0 into the textbox and pour. Record the amount transferred to the beaker. 11. Record the mass of the alcoholic beverage and beaker. 12. Calculate the density of the alcoholic beverage. 13. Record all data to the appropriate number of significant digits in your laboratory notebook. 14. Repeat the experiment using a 10mL pipette found under the "Glassware' tab. When withdrawing liquid with the pipette, enter 10.00 into the textbox. 15.
