Homework Help: Physical Chemistry

Posted by Anonymous on Monday, May 24, 2010 at 2:50pm.

When 1.33 g of a nonpolar solute was dissolved in 50.0 g of phenol, the latter's freezing point was lowered by 1.454C. Calculate the molar mass of the solute. The kf of phenol is 7.27 (Kkg)/mol.

What is the normal boiling point of an aqueous solution that has a freezing point of -1.04C?
The kf of water is 1.86 (Kkg)/mol and the kb of water is 0.51 (Kkg)/mol

I am having a diffculty time with coming up with the answer when dealing with freezing and boiling points? Thank you for the help!
