Question

A solution of Chlorine (notChloride) and Carbon disulfide, CS2 hasa density of 1.22 g/mL. The mole fraction of Chlorine is 0.220.

Convert this mole fraction into the following concentrationexpressions:

Since it doesn't state how much solutionyou have, assume you have 1.00 total moles(solute + solvent). Then a mole fraction of 0.220 wouldcontain 0.220 molesChlorine.

A Map of Concentration Units and the relationships betweenthese units and Molarity, molality, mass %, ppm, and mole fractioncan be found under the ReferenceMaterial link and then the Expressing Concentrations link (or click here).

Reconstruct this Map of Concentration Units on a sheet of paper andplace the numbers in red in theirappropriate places. Fill in the rest of the Map and then use theinformation in the Map to express the solution's concentration inthe terms below.



Molarity
molality
Mass Percent Chlorine
Parts per million Chlorine
Mole fraction Carbon disulfide, CS2
5. Vitamin K (a non-electrolyte) is involved in the bloodclotting mechanism. When 0.510 g is dissolved in 9.999 g of camphor(C10H16O), thefreezing point is lowered by 4.50 oC. Calculate themolecular weight of Vitamin K.

KfC10H16O = 40.0 oC/m

Freezing Point Camphor = 179.50oC ________ Molarity
molality
Mass Percent Chlorine
Parts per million Chlorine
Mole fraction Carbon disulfide, CS2
