Hey
I want to replace oil
Volume = 1500ml
I can just get 250ml out at once then i have to refill it with fresh oil... the oil mixes 100%
So:
Step 1:
1500 old oil -> 250 ml out and 250ml fresh in
Step 2:
1250 old oil 250ml fresh oil
When i let 250ml out and refill with fresh oil:
1040 old oil 460ml new oil....
So how many times i have to repeat that to get 95% new oil ??
hang on op
imma try to work it out

http://math.stackexchange.com/questions/971202/is-my-interpretation-on-the-specific-replacement-in-a-solution-is-correct-or-not
see if this helps
basically
u have to solve
(5/6)^x = (1-.95)
find n by taking logs
umm solve for x
not n
that was a typo
roughly 17 times
glad top help
with every iteration
you dilute your conc to 5/6 th
(1500-250)/1500
