What is the boiling point of a 0.75-molal solution of a non-volatile non-electrolyte solute in water? kb for water = 0.52 degrees c/ molal.
99.61 °c
100.0 °c
100.39 °c
101.44 °c

Take the molality and multiply it by the Kb
0.75 × 0.52 = 0.39 C

then add the boiling pt to the 0.39
100 + 0.39 = 100.39 C

The answer is C. I just did this assignment

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
