Step 1:I'll solve this problem step by step, following the specified LaTeX formatting guidelines:
Step 2:: Understand the Concept
Milliequivalents (mEq) are a way to express the chemical combining power of an electrolyte. For potassium, we'll need to know the typical potassium content in a banana.
Step 3:: Typical Potassium Content
An average banana contains approximately 422 mg of potassium.
Step 4:: Calculate Milliequivalents
- Valence of potassium = $$+1
To convert mg to mEq, we need to use the atomic weight and valence of potassium:
Step 5:: Conversion Calculation
\text{mEq} = \frac{422 \mathrm{~mg}}{39.1 \mathrm{~g/mol}} \times \frac{1 \mathrm{~mol}}{1000 \mathrm{~mg}} \times 1
Step 6:: Final Calculation
\text{mEq} = \frac{422}{39.1} \times 1 = 10.8 \mathrm{~mEq}
Final Answer
A banana contains approximately 10.8 \mathrm{~mEq} of potassium.
