# Coke using the calibration curve Essay

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 120z 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 urve 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. Data: 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) pure H20 44.

The calibration curve is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

The equation that was used to figure or the number of grams of sugar in a can of coke is FO. 03673x+O. 9946 (slope). The y in this equation is 1. 040g/ml and this was found by subtracting mass of the flak with the substance and the mass of flack without the substance and what you get from that you divide by 100 and you get you y and then you only solve for x and in the graph it shows that the x and y match with the regression line.

The process of finding this conclusion was that we (my partner and myself) needed to have five different solutions to use so we can test it out. The process was to weigh in grams the flask, sugar, sugar in the flask, water mixed with sugar in flask, and repeat five times and in each test we raised the grams in sugar orm one trough seven. This let us to find the density of the solution of not Just one but five and the dissolved solution of five different test results.

From that we put it in the graph and as a result the sugar in the can of coke was in the peek and it had the highest density of sugar in grams. The errors of this experiment that the amount of sugar were rounded up and this gave a higher amount of grams of sugar then exact amount of sugar in a can of coke. The exact amount of sugar in a 120z can of coke is 39 grams (said online by the Coke-Cola company). In conclusion, the amount of sugar of a can of coke we used is 43. 83g.
