... It became known as the colour blue but that was just someone's opinion! Thus, the colour 'green' may actually be 'lilac' and what not. There is no substansial evidence to prove that any colour is exactly how we see it. The way I see it is, someone decided to call blue - blue... They assumed that name would be fit. But as you know, assumptions cans be dangerous - especially when looking at the question philosophically.

Please offer your opinions only.

I'm doing a project on the effects of prescription painkillers and of overdoses of the medicines. Is there a specific way to find out the lethal dose of them? I know for some (like ibuprofen) a specific lethal dose won't be available, but for some (such as acetominphen and codeine), I'm sure there must be a Poison Control database around somewhere.

I am not looking for courses in calculus, which are more for freshmen. A few examples of what I am looking for are Number Theory and College Geometry.

I am also not interested in universities that only exist online, such as Phoenix and Walden.

Thanks.

Seawater contains 3.4 g of salts for every liter of solution. Assuming that the solute consists entirely of NaCl (over 90% is), calculate the osmotic pressure of seawater at 23°C.

By using the formula osmotic pressure=(molarity)(temperature)(R), I got this...
1. M=mol/L=(3.4/58.4)/1 [because it says per liter]
2. T=23+273=296
3. MTR=1.41
...but the answer I got was wrong, so I tried multiplying the moles by .9 (thinking the 90% part was important), but the answer was still wrong. Any ideas?
