What is the mole fraction of solute in 0.5 molal aqueous solution?
0.5 molal solution means 0.5 moles of solute in 1 kg of water. The molar mass of H2O = 18.015 g/mol.
What is the mole fraction of solvent in 2.5 molal aqueous solution?
2.5 m aqueous solution means that 2.5 moles of the solute are dissolved in 1000 g of water. (2.5mol)(2.5mol+55.5mol)=(2.5mol)(58mol)=0.043.
What is the mole fraction of the solute in a 2.00 m aqueous solution?
Mole fraction of solute =(2 mol)(2 mol)+(55.55 mol)=0.347.
What is a .5 Molal solution?
5 molal solution means 5 moles of solute are dissolved in 1 kg (or 1000 g) of solvent.
What is the mole fraction of solute in 1?
D) 1.770. Hint: Mole fraction of a solute in a binary solution is the ratio of the number of moles of solute to the total number of moles of the solution. The total number of moles of the solution includes the number of moles of the solute and the number of moles of the solvent.
What is the mole fraction of a solute in one?
A mole fraction, as the name implies, is a comparison of the number of moles in solution. It is found by taking the number of moles of solutes (or solvent) divided by the total number of moles (solutes + solvent). Since this is a fraction, there are no units. The mole fractions of a solution must add up to one.
What is the mole fraction of h2o2?
Thus the mole fraction of hydrogen peroxide in a 30% aqueous solution of hydrogen peroxide is 0.184.
What is the mole fraction of rectified spirit?
Rectified spirit is the highly concentrated form of ethanol which contains 95% ethanol by weight. The mole fraction of the ethanol in the rectified spirit will be the number of moles of ethanol with respect to the total number of moles in the spirit.
What is the mole fraction of methyl alcohol?
Therefore, the mole fraction of methyl alcohol in the solution is 0.086.
What is the relation between molality and mole fraction?
The mole fraction of any component of a solution is defined as the ratio of the number of moles of that component present in the solution to the total number of moles of all the components of the solution. Molality is defined as the total moles of a solute contained in a kilogram of a solvent.
