The average density of a fraction x of water of density .984 and a
fraction y of alcohol, density .786, must be equal to that of olive oil,
X*0.984+Y*0.786=0.904 (eq 1)
and because X and Y are fractions of the whole and there is no other
X=1-Y (eq 2)
(eq 2) into (eq 1):
~59.6 % water
~40.4 % alcohol
This is assuming that the water and alcohol don't react (don't even
bind); to be honest i'm not sure they absolutely don't, and if they do,
that would change the calculations.
Why do i feel i just gave _you_ the answer to _your_ homework due first
thing tomorrow morning???
