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 135 lb (61.2 kg ) is 5.74×10−3 mol . What volume of a 0.0640 M KCN solution contains 5.74×10−3 mol of KCN? Express the volume to three significant figures and include the appropriate units.
I think probably diet because the type of food you put in your body (if it has high calorie or sodium) can severley affect your overall health and therefore affect your bpm(beats per minute)
