Derek Hull Lab #7 03/17/10 pg 57 Questions 1) The highest were Cranberry Juice and Coke out of our results. The lowest were Sugar Free Red Bull and Diet Coke. 2) For every drink except one (Cranberry Juice), our results had a higher sugar concentration than what the label said was in the drink. One source of potential experimental error was that we did not have the hydrometer calibrated accurately. 3) No I do not agree with the statement “Fruit juices and energy drinks are better for you than.” I do not agree because Coke was the only soft drink that we found to have higher sugar concentrations than the fruit juices and energy drinks. It was not the highest total that was cranberry juice. 4) 355 mL /12 oz equals 29.6 mL/oz, which is the conversion factor for ounces to

Unformatted text preview: grams. 20 oz times 29.6 mL/oz equals 592 mL in one serving. There is 11 g of sugar per 100 mL so there is 55 g of sugar with 92 mL left. 92 is 92% so 92% of 11 g gives us another 10.12 g of sugar. So the total amount of sugar in Coke is 65.12 g. That equals roughly 19 packets of sugar (65.12 g/ 3.5 g) 5) A) You would switch the axis labels. Concentration would be the y-axis and height would be the x-axis. B) Adding alcohol would decrease the density of the solution. C) The higher the concentration of alcohol, the lower the hydrometer would be and the lower the concentration, the higher the hydrometer would be. 6) Coke cans would float because it has a higher density and Diet Coke cans would sink because it has a lower density....
