Question

Carbonated beverages are manufactured to dissolve carbon dioxide gas at high pressure that is released when the can is opened so that the beverage is more refreshing to the consumer. How many grams of dissolved carbon dioxide is in a 355mL can of soda at 20 degrees Celcius if the manufacturer used a pressure of 2.4 atm of CO₂ to carbonate the pop? The Henry's law constant for carbon dioxide dissolving in water is 3.5*10^-2 mol/L*atm at 20 degrees Celcius.

Answer 1

prepare The equilibrium for dissolving con gas to carbonated beverager is written as: CO2 (gas) - coa (in Liquid) If the pressure of coa (gas) is Peos concentration of cl in the soda O2(gas) is c then , & according and if the aften dissoring the Henry low to - 2 e = K Peop where K » Henry's law constant notat we here, Peso = 204 atm Was HK = 305 x 102 mol/L.atm. sa e = 3.5 xjö? mol.
