100 mL of ether was divided into two portions of 50 mL each and two extraction was performed. How much A will be extracted after two extraction of 50 mL each.
The ratio of solubilities in the two solvents is called the distribution coefficient, KD = C1/C2, which is an equilibrium constant with a characteristic value for any compound at a...

What is the mass fraction and volume fraction of an aqueous solution having 0.7304 Mol Fraction, 0.6268 Specific Gravity of solute and 42.00 Molar Weight of solute?
Molar mass of solvent = 42/ 0.6268= 66.8789Total mass= 66.8789 + 42= 108.8789Mass fraction= 42/108.8789= 0.3857Volume fraction = 0.3857/ 0.7304=0.528

An aqueous solution has 18% of solute. By chemical analysis, it was known that it has 10 mol% solute.
What is the molecular weight of the solute?
m = n*M, m - weight, n - quantity of substance, M - molecular weight mx /18 = mH2O / 82nx = nH2O / 9nx *Mx = nH2O * MH2O*18/82Mx...

A solution is composed of one mole of non-volatile solute and four moles of volatile solvent. If the vapor pressure of the pure solvent is 20 torr, what is the vapor pressure of the solution?
The solute is non-volatile, so the vapor pressure will be equal to the pressure of the solvent. According to Raoult's law: Pi = xiPoi where xi is a mole fraction,...

Why is it better to do three extractions with say 10mLs of each rather than one large extraction with 30 mLs of solvent?
Answer: the extraction process is characterized by a constant distribution of the extracted substance between the two solvents. This constant does not depend on the concentration, but depends on the...

The melting point of a pure solvent is -116.3 C. If 352 g of an ionic solid is added to 567.7g of the solvent, the new melting point is -121.6 C. What is the molar mass of the ionic solute?
delta T = i•Kf•molalityMolality = moles / kg solventYou have molality and kg solvent, solve for moles.Moles = grams / molar mass. You have moles and grams, solve for molar...
