The air trapped inside a can of Diet Dr$.$ Pepper soda is pure carbon dioxide at a pressure of $2$ atm.

a$.$ What is the concentration of carbon dioxide in the soda in units of $mo\frac{l}{L},\frac{g}{L},$ and $ppm$ before any of it dissociates in part $b$ below?

b$.$ The carbon dioxide in the soda will change to carbonic acid $($assume $[C{O}_2]=[H_{2}C{O}_3]),$ and carbonic acid is a weak acid. Using what you know about weak acids, what is the $pH$ Using a ice table!
