How would you make 300ml of a mixture of toluene and hexane in a ratio of 70:30 respectively?
~I really don't know how I would do this...would I do this?:
xT + yH= 300ml
xT= 300ml- yH
then plug that in? That came out funny though since I get 0 in the end...

I assume this is a volume ratio.
70 + 30 per 100 mL.
270 + 90 per 300 mL.
