Chemistry · Different methods for expressing the concentration of solution: molality, molarity, mole fraction, percentage (by volume and mass both)
The concentration of dissolved oxygen (DO) in cold water can go upto:
The concentration of dissolved oxygen (DO) in cold water can go upto:
- A. 10 ppm
- B. 14 ppm
- C. 16 \mathrm{ppm} \)
- D. 8 ppm
Step-by-step solution
Dissolved oxygen (DO) in water is inversely related to temperature. In cold water (near 0°C), the saturation concentration of oxygen is approximately 14.6 ppm. Among the given options, 14 ppm is the closest and standard value.
