QuestionA farmer uses $1455 \mathrm{~kg}$ of fertilizer with $10.0\%$ nitrogen. If $15.0\%$ washes into a river flowing at $0.410$ ft³/s, find the nitrogen concentration in mg/L added to the river yearly.

Studdy Solution
Calculate the concentration of nitrogen in the river water.
$$Concentration\, of\, nitrogen =21825000\, mg /366080000\, liters =0.0596\, mg/L$$The additional concentration of nitrogen in the river water due to the farmer's fertilizer each year is0.0596 mg/L.
