Prepare me a drink, buddy
Gather up, friends, to do some cool bits of physical chemistry.
Here's my question:
What volume of 75% Alcohol ( of density = 0.8 g/mL) must be used to prepare 150 mL of 30% Alcohol (of density = 0.9 g/mL)?
Nice and detailed solutions are very welcome!
And oh, I hope the title was a little funny. I'm not very good at those.
The answer is 67.5.

4/5 x 0.8 x v x 75/100 = 150 x 0.9 x 30/100..............By solving this for v, we get v = 67.5 mL
