We have determined the serum content of vitamin B12 by microbiologic assay in patients with acute and chronic liver disease and have investigated the absorption, the urinary excretion and the plasma clearance of radioactive vitamin B12.
The amount of gallons of water in a pool varies greatly depending on the size of the pool. The average in-ground backyard pool holds between 18,000 and 20,000 gallons of water.
Divide the number of gallons in the pool by 120,000. All pool measurements are in parts per million. One pound of pure chlorine will raise the chlorine concentration of 1 million pounds of water by one part per million.Therefore, adjust the pool in question by the ideal pool of 120,000 gallons, or 1 million pounds of water.ivide the number of gallons in the pool by 120,000.
