The theoretical oxygen dmenad of a 0.001 mol/L glucose solution

Home » Water Requirements » Water requirements miscellaneous » Question

The theoretical oxygen dmenad of a 0.001 mol/L glucose solution is

1. 180 mg/L
2. 192 mg/L
3. 90 mg/L
4. 96 mg/L

Correct Option: B

Glucose: C₆H₁₂O₆

0.001 mol/L of glucose = 180 × 0.001 g/litre
= 180 mg/L glucose
From the equation 180 parts glucose need 192 parts oxygen.
∴ 180 mg/L glucose need 192 mg/L oxygen
