The lethal dose of potassium cyanide (KCN) in Rats is 10mg KCN per kilogram of body weight. What is the concentration in parts per million (ppm)
Potassium cyanide is a toxic substance, and the median lethal dose depends on the mass of the person or animal that ingests it. The median lethal dose of KCN for a person weighing 145 lb (65.8 kg) is 7.27Ă—10^(-3) mol. What volume of a 0.0820 M KCN solution contains 7.27Ă—10^(-3) mol of KCN?
