(choose chapter or problem)

The solubility of \(\mathrm{CO}_{2}\)gas in water is 0.15 g/100 mL at a \(\mathrm{CO}_{2}\) pressure of 101,325 Pa.

(a) What is the solubility of \(\mathrm{CO}_{2}\) in a soft drink (which is mainly water) that was bottled under a \(\mathrm{CO}_{2}) pressure of 4.6 x  \(10^{5}\)Pa?

(b) An atmospheric concentration of 380 ppm, \(\mathrm{CO}_{2}\)corresponds to a partial pressure of 38.5 Pa. What percentage of the \(\mathrm{CO}_{2}\) originally dissolved in the solution in part (a) remains in solution after the soft drink reaches equilibrium with the ambient atmosphere?

(c) One bottle of soda is stored in a refrigerator at 3 \({ }^{\circ} \mathrm{C}\)(276 K), and another is stored at room temperature (25 \({ }^{\circ} \mathrm{C}\)or 298 K). If both bottles are opened simultaneously, which one would exhibit greater carbonation (i.e., bubbles)? Explain.
