Question
**Question 14**: The concentration of the original unknown protein solution is determined to be 0.2173 mg/mL. What is the protein concentration in the units of parts-per-million (ppm)? One ppm = 1 mg/L. - ○ 0.217 - ○ 4602 - ○ 217.3 - ○ 217 **Explanation**: To convert the concentration from mg/mL to ppm: 1 mg/mL = 1000 mg/L (since there are 1000 mL in a liter, the concentration must be multiplied by 1000). Thus, 0.2173 mg/mL = 0.2173 x 1000 mg/L = 217.3 mg/L, which is equivalent to 217.3 ppm. The correct answer is 217.3 ppm.
