Record the mass on a table labeled ” Data Table A” ) Zero out the scale. ) Dry Pipet 6) Repeat steps 2-5 for the rest of the sugar references and record the mass on the data table. Always rinse and dry the pipet after every procedure. When done measuring, pour the sugar references back into the designated glass. Don’t forget to zero out the scale. 7) Get the density for each solution and record it on the table. Part B 1) Make another data table and now use two different beverages and find their density. Record the mass and volume on data table B. Always rinse the pipet before ontinuing. . Pre-Lab Questions: 1) If the following mass and volume data are used to calculate the density of solution, how many significant figures are allowed in the calculated density? Mass of solution- 12. 53 g; volume of solution = 8. 27 There would be only 3 significant figure allowed in the calculated density. 2) Calculate the density of the solution described in Question #1. The calculated density is 1. 52 3) According to its nutrition label; orange soda contains 49 gof sugar per 355-mL serving.
If the density of the beverage is 1. 043 g/mL, what is the ppercent sugar concentration in the orange soda? Hint: This is a 2-step problem. First, use the density to convert the 355 mL serving size to grams. The calculate ppercent in the beverage. The ppercentage of the sugar concentration in orange soda is 13%. 6. Calculations/Analysis : 1) Plot the known density on the y-axis versus the sugar on the x-axis for the following sugar references. Use a ruler and draw a “best fit” straight line. By ohliane
