How many cups of coffee would it take for a 200 lb person to reach their LD50 of caffeine if they had a 12 fl oz cup and there was 100 mg of caffeine per 6.0 fl oz cup?
The ld50 for humans varies depending on sensitivity of the person- between 150 and 200 mg per kilogram of weight. Using the lower value, that would be over 68 of the 12 oz cups in a very short period of time. Unlikely to happen, as ingestion of 6.3 GALLONS of coffee in a short time frame (half hours) is almost impossible.
When you mix coffee with water to make a cup of coffee is the coffee an impurity?
As opposed to pure water? yes. i suppose it could be considered an impurity if you are striving for pure water. But if your goal is to make coffee, and the 2 ingredients you need are hot water and coffee, then no, i would not consider coffee and impurity. In that case, milk, or salt, or murcury, or dog feces would all be considered impurities in your pure cup of coffee. Purity in this case is really a matter of perspective

Why does a powdered drink dissolve in water?
Caffeine is actually a non-polar substance, and normally would not dissolve in water, but since it contains some polar bonds it is able to dissolve in hot water. This is how they decaffeinate coffee, the coffee beans are soaked in hot water and all the flavoring, caffeine and aroma are extracted. Then it is put through a carbon filter which holds back all the caffeine so the flavoring and aroma can be added back into the bean, roasted, and ground to make you morning cup of decaffeinated coffee!
