The consumption of dissolved oxygen in water by sugar.

A large pond is 300m by 95m with an average depth of 2.5m. Assuming that the pond is saturated with oxygen, calculate the amount of sugar (C12H22O11) in kg that would be sufficient to completely consume the dissolved oxygen.

Solution Preview

Molecular weight of sugar = 12*12 + 1*22 + 16*11 = 342 gm
Molecular weight of Oxygen = 32 gm

Dissolved oxygen,
DO = {(P-p)/(35+t)} - 0.678

For P = 1 ...

Solution Summary

This solution includes calculations for volume, dissolved oxygen, water vapor pressure, and moles and mass of sugar needed.
