how much oxygen would be found in 10.0gal of water at 20c

To calculate the amount of oxygen dissolved in water at a specific temperature, you need to know the dissolved oxygen concentration at that temperature. This value can be determined using an oxygen solubility chart or an oxygen solubility equation.

The solubility of oxygen in water depends on temperature, so we need to find the solubility value for oxygen at 20°C. Let's assume the solubility of oxygen at 20°C is 9 mg/L (milligrams per liter).

To calculate how much oxygen would be found in 10.0 gal of water at 20°C, we'll need to convert the volume from gallons to liters.

1 gallon is approximately equal to 3.785 liters.

So, 10.0 gallons of water is equivalent to:

10.0 gallons * 3.785 liters/gallon = 37.85 liters of water.

Now we can calculate the amount of oxygen dissolved in the water.

Oxygen concentration (mg/L) = Solubility of Oxygen (mg/L) * Volume of Water (L)

Oxygen concentration (mg/L) = 9 mg/L * 37.85 L

Oxygen concentration (mg/L) = 340.65 mg/L

Therefore, there would be approximately 340.65 mg of oxygen dissolved in 10.0 gallons of water at 20°C.
