Nvm. I got it. It wasn't so hard after all :D

chemistry
How many milliliters of a 15.0%, by mass solution of KOH(aq) ( d= 1.14g/mL ) are required to produce 27.0 L of a solution with pH = 11.70? I'm really not sure how to do this, it's from Acids & Bases chapter. Any help is appreciated, thanks. (:

Chemistry: molality and freezing point?
Silly meee!! This question is already answered. :)

Chemistry: molality and freezing point?
What mass of ethylene glycol C2H6O2, the main component of antifreeze, must be added to 10.0 L water to produce a solution for use in a car's radiator that freezes at -23.3C? Assume the density for water is exactly 1g/mL. m = moles solute / kg solvent Help please?

CHEMISTRY!
I don't understand why is it 10kg solvent?
