Chapter 18, Problem 47E

The organic anion

is found in most detergents. Assume that the anion undergoes aerobic decomposition in the following manner:

$\begin{array}{l}{\text{2 C}}_{\text{18}}{\text{H}}_{\text{29}}{\text{SO}}_{\text{3}}^{\text{-}}\left(\text{aq}\right){\text{ + 51 O}}_{\text{2}}\left(\text{aq}\right)\to \hfill \\ {\text{36 CO}}_{\text{2}}\left(\text{aq}\right){\text{ + 28 H}}_{\text{2}}\text{O}\left(\text{l}\right){\text{ + 2H}}^{\text{+}}\left(\text{aq}\right){\text{ + 2SO}}_{\text{4}}^{\text{2-}}\left(\text{aq}\right)\hfill \end{array}$

What is the total mass of O₂ required to biodegrade 10.0 g of this substance?
