Step 1:
I'll solve this step by step using the precise LaTeX formatting guidelines you specified:

Step 2:
: Understand the Conversion

A 5% solution means 5 grams per 100 mL of solution. We need to convert this to mg/mL.

Step 3:
: Convert Percentage to Grams per 100 mL

5\% = \frac{5}{100} \times 100 \mathrm{~mL} = 5 \mathrm{~g}/100 \mathrm{~mL}

Step 4:
: Convert Grams to Milligrams

5 \mathrm{~g} = 5 \times 10^{3} \mathrm{~mg}

Step 5:
: Calculate mg per mL

\frac{5 \times 10^{3} \mathrm{~mg}}{100 \mathrm{~mL}} = 50 \mathrm{~mg}/\mathrm{mL}

Final Answer

The key steps were converting the percentage to grams, converting grams to milligrams, and then dividing by the volume to get mg/mL.
