A soft drink was bottled with a partial pressure of $$\text{CO}_2$$ of $$3\,\text{bar}$$ over the liquid at room temperature. The partial pressure of $$\text{CO}_2$$ over the solution approaches a value of $$30\,\text{bar}$$ when $$44\,\text{g}$$ of $$\text{CO}_2$$ is dissolved in $$1\,\text{kg}$$ of water at room temperature. The approximate pH of the soft drink is __________ $$\times 10^{-1}$$. (First dissociation constant of $$\text{H}_2\text{CO}_3 = 4.0 \times 10^{-7}$$; $$\log 2 = 0.3$$; density of the soft drink $$= 1\,\text{g mL}^{-1}$$)
