### Dissolved Oxygen and Water - USGS

Oct 22, 2019·The oxygen content of surface waters of normal salinity in the summer is typically more than 8 milligrams per liter (8 mg/L); when oxygen concentrations are less than 2 mg/L, the water is defined as hypoxic (CENR, 2000). The hypoxia kills many organisms that cannot escape, and thus the hypoxic zone is informally known as the “dead zone.”

### Air-fuel ratio, lambda and engine performance – x-engineer

In that step you have converted to grams, so you should have used the percentage of weight. In fact, oxygen constitutes 23.14% of the air by weight. So if the fraction were 23.14/100, then the MAir=(100/23.14)*MOxygen=4.322*63.996=276.56 grams. This yields an Air to Fuel Ratio by weight of 17.24. Much closer to the chart.
