You are watching: Density of coke and diet coke
Density to represent the relationship in between a substance's mass and the amount of an are it occupies, i.e., the volume. Scientists typically express density in metric systems of grams every milliliter, or g/mL. Pure water exhibits a thickness of 1.00 g/mL. Most other liquids exhibit densities in between 0.8 and also 1.3 g/mL.
Coca Cola consists mostly that water. However it additionally contains 39 g the sugars, mostly in the type of high-fructose corn syrup, or HFCS. The HFCS used by Coca-Cola and most various other soft drink manufacturers exhibits a relative sweetness that 160 compared to the baseline sweetness of 100 showed by sucrose, or table sugar. This relative scale reflects viewed sweetness, which method that HFCS accurate tastes 1.6 time sweeter than an equal amount that sucrose. As a result, a drink sweetened v HFCS requires less sweetener to attain the desired level the sweetness than a drink sweetened v sucrose.
Diet Coke includes an man-made sweetener: aspartame. Aspartame exhibits a perceived sweetness that 180 times the of sugar. Or, for a more direct comparison, aspartame exhibits a sweetness 113 times better than high furustos corn syrup. Together a consequence, Diet Coke only requires 0.35 grams the aspartame to accomplish the very same level the sweetness together the 39 g of HFCS in Coke.
Whether an object sinks or floats counts on that buoyancy. An object placed in water exerts a downward pressure on the water. The water, however, pushes back. Archimedes' principle claims that the buoyant pressure exerted through water or any other liquid on an object is equal to the weight of the water displaced by the object. If the load of displaced water exceeds the load of the object, the object floats. Otherwise, that sinks. This, in part, describes why steel ships float. It likewise explains why the have the right to of Diet Coke sinks. Due to the fact that the two cans exhibit identical shapes and also sizes, they displace equal quantities of water once submerged. Yet the reality that the have the right to of Coke sinks means it must weigh an ext than the lot of water that displaces, conversely, the can of Diet Coke weighs less.

Both the Diet Coke and Coke can be ~ contain 12 fluid oz., or 355 milliliters, that liquid. Both beverages consist mostly of water. The primary difference lies in the sweetener. Coke contains around 325 mL that water, through a density of 1.0 g/mL, and also 39 g that sugar. The materials of the can therefore weigh 325 g + 39 g = 364 g. The deserve to of Diet Coke, however, contains only 0.3 g that aspartame. It as such consists almost entirely that water and also the can's contents because of this weigh about 355 g. This distinction in weight makes the can of Diet Coke saturated buoyant to float. In terms of density, the density of Diet Coke is approximately 1.00 g/mL, the exact same as water. The Coke, however, exhibits a thickness of 1.03 g/mL.
