Depression in freezing point is denoted by,

Freezing point of water + Freezing point of solution

From the given data

But

Where freezing point depression constant

for water

A solution is made by dissolving 1.25 g of C2H5OH in 11.6 g of H2O. Calculate the mass percent of C2H5OH, the mass percent of H2O, molality of C2H5OH.

Mass of C2H5OH = 1.25 g Mass of H2O = 11.6 g Mass percent of C2H5 OH = 1.25 × 100 / 1.25 + 11.6 = 125 / 12.86...

A solution of ethanol is prepared by dissolving 25.0 ml of ethanol in enough water to give a total volume of 250.0 ml. What is the percent-by-volume concentration of ethanol?

percent v/v is (mL ethanol/mL solution)×100.So you have 25.0 mL ethanol/250 mL(25/250)×100 = 10% v/v.

A sample of rubbing alcohol solution contains ethanol, C2H5OH(l). If the sample contains 1.25x10^23 atoms of hydrogen in the ethanol, what amount in moles of ethanol is in the sample?

The amount of moles for atom\molecule\compound etc. can be calculated based on amount of atom\molecule\structural units etc. using Avogadro constant (NA=6.02x10^23) that represents 1 mole. One molecule of ethanol consists...

A sample of a wine contain 28% C2H5OH by volume and rest is H2O. Calculate mole fraction of C2H5OH in wine, density of C2H5OH = 0.79 gm/ml, density of water = 1 gm/ml.

0.28 x 0.79 = 0.22 g.0.22/46 = 0.004 .

What is the boiling point of a 0.66 molal solution of sucrose (nonelectrolyte) in ethanol? (Kb of ethanol = 1.22 °C/m, normal boiling point of ethanol is 78.5 °C)

∆Tb=Kb*Cm=1.22*0.66=0.81 °C;Tb(solution)=78.5 - ∆Tb=77.69 °C;Answer: 77.69°C
