### Reaction Rate Problem

At a certain temperature, the rate of this reaction is second order in \( \text{NH}_4\text{OH} \) with a rate constant of \( 0.0112 \, \text{M}^{-1} \cdot \text{s}^{-1} \):

\[ \text{NH}_4\text{OH} \, (\text{aq}) \rightarrow \text{NH}_3 \, (\text{aq}) + \text{H}_2\text{O} \, (\text{aq}) \]

Suppose a vessel contains \( \text{NH}_4\text{OH} \) at a concentration of \( 0.780 \, \text{M} \). Calculate the concentration of \( \text{NH}_4\text{OH} \) in the vessel \( 430. \) seconds later. You may assume no other reaction is important.

Round your answer to 2 significant digits.
