Hi.
How many grams of antifreeze must be dissolved in 300 g of water in order to reduce the freezing point of water to –13.02o C under 1 atm pressure (Kf: 1.86 o C/molal and C3H5(OH)3: 92.09 g/mol).
I have not learned molality yet and I am completely confused as to where to start. I only know that molality = moles of solute / solvent. If someone could please take a look at this question and perhaps explain to me the steps to solving it, I would really appreciate it. Thanks.
