Question

The precise ingredients in coke are trade secret, but from the nutritional information on a bottle of coke, we can see that the most important ingredient is sugar: 10.6g per 100 ml. For the purposes of this question, you can model coke as a %u2018dilute%u2019 solution of fructose (C6H12O6) dissolved in water.

Suppose the bottle of coke is sealed by a semipermeable membrane, which allows water, but not the sugar molecules, to diffuse through . How much pressure would the bottle need to withstand if you now placed it under water?
