It would be the total molality of ALL of the solutes - note that if it is an ionic compound that completely disociates, you might need to multiply it by a factor - for example, MgCl2 would break into three ions so its amount would have a triple effect.
@@JonBergmann1 okay, say for example I have etyhlene glycol and MgCl2 solved in water. I have 200 g glycol and 200 g MgCl2 and 600 g of water. Could I do like this: 200g glycol/62.07 (molar mass)=3.2. It has i factor=1 so then I take 3.2/0.6 (water in kg)=5.4. Then I multiply that with 1.86 (constant for water) and get 10 degrees. Then I do the same thing for MgCl2 but use I factor= 3 instead. So 200/95=2.1 moles. 2.1/0.6 times 1.86 times 3 which is 20. Then I add 20 to 10 and get 30. So the frezzing point should be 0-30=-30. Is this correct?
Hi teacher how I can solve difficult problems about boiling point elevation, freezing point depression, osmotic pressure and vapour pressure? Please answer this question
Hey my good sir! This video is very informative, I'd like to thank you for that. But can you do something about the screeching of the pen? Thanks hehehe
