In cryoscopic determination of molar mass, teh molar mass in g mol^-1 is given by M=1000wKf/(W(deltaTf))(1-kf(deltaTf), derive a formula for the relative error in the molar mass using the approximate equation M=1000wKf/(W(deltaTf)) ...
A solution of glycerol(C−(3)H8O3, molar mass = 92 gmol−1iin water was prepared by dissolving some glycero 500 g of water. This solution has a boiling point of100.42∘C. What mass of glycerol was dissolved to make this solution ?Kbfor water=0.512kkgmol−1. ...
To estimate the molar mass of the unknown gas based on the molar mass of argon, which assumptions should be made? Check all that apply. The pressure is the same for both argon and the unknown gas. The atomic radii is the same for both a...
