Question
**Chemical Reaction Rate Problem**

In this exercise, we are asked to determine the rate at which Br⁻ (aqueous) disappears in a chemical reaction under given conditions. The specific reaction is as follows:

\[ \text{BrO}_3^- + 5 \text{Br}^- + 6 \text{H}^+ \rightarrow 3 \text{Br}_2 + 3 \text{H}_2\text{O} \]

Given Condition:
- The rate of disappearance of BrO\(_3^-\) (aqueous) is 0.046 M/s.

Task:
- Calculate the rate at which Br⁻ (aqueous) disappears.

**Interactive Calculator:**
To assist with calculations, use the on-screen number pad, including operations like multiplication (×), division (⁄), and powers of ten (×10).

**Rate Expression:**
The rate of disappearance of Br⁻ with respect to BrO\(_3^-\) can be determined from the stoichiometry of the reaction. Multiply the rate of BrO\(_3^-\) disappearance by the stoichiometric coefficients.

Enter your result below in M/s:

\[ \_\_\_\_\_\_\_ \text{M/s} \]

This problem helps in understanding stoichiometry and reaction rates in chemical kinetics.
