About Me "When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts advanced to the state of science, whatever the matter may be."
Sir William Thomson (Lord Kelvin) 1883

It's not that simple: you need to account for the vapour pressure and the molar fraction of each component in the liquid mixture.
