To find the oxygen saturation level of the lake, divide the amount of dissolved oxygen in the lake's water per liter ( 7.4 mg/L ) by the water's dissolved **oxygen **capacity per liter (9.4 mg/L) to get the proportion. Multiply this by 100 to convert it into a percentage (78.72%), which rounds to 79% saturation. ;
The oxygen saturation of the lake is calculated to be 79%. This is determined by dividing the dissolved oxygen amount (7.4 mg/L) by its capacity (9.4 mg/L) and converting that ratio into a percentage. Oxygen saturation is essential for the survival of aquatic life.
