Lab: How much sugar is in a Can of Coke?
Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke.
Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration curve. 5 different solutions were made, each containing 100mL of water and between 1 and 7 grams of sugar. The calibration curve was used to determine the sugar in the can of Coke. The measurements used are grams and milliliters. The calibration curve is used to determine the grams of sugar just by using the density of the can of Coke. In this experiment the main equation was density = mass / volume.
Mass of empty flask and stopper (g)
Mass of flask and stopper with sugar (g)
Mass of flask and stopper with solution (g)
Mass of Sugar (g)
Mass of Solution (g)
Density of Solution (g/ml)
Dissolved sugar per mL solution (g/ml)
Results: See separate page.
Discussion: Overall the experiment successfully show that there is about 43.83g of sugar in a can of Coke using the calibration curve. The calibration curve is a general method for determining the concentration of a substance in an unknown sample by comparing the...
