Explain the environment to give harmless products

Reference no: EM13502235

It is very desirable that pesticides eventually decompose in the environment to give harmless products. Let us assume the half life for the first order decomposition of a certain pesticide is 10.2 years. If the present concentration of a pesticide in a lake is 3.0 x 10^ -8 M, what was the concentration 4.00 years ago?
