What is the mole fraction of a solute in one molal aqueous solution?

What is the mole fraction of solvent in 1 molal aqueous?

1 molal aqueous solution means that 1 mol/kg that is 1 mol of solute is present in the 1000 g of the water(here the aqueous means that solvent is water). The mole fraction of solvent in 0.1 molal aqueous solution is 0.9982.

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 solute in 2 molal aqueous solution?

i.e. 2 moles of solute in 1000 g of H2O. n1 = 1000/18 = 55.56 mol . x2 = 2/57.56 = 0.0347 .

What is the mole fraction of the solute in a 1.0 molal aqueous solution?

0.0177.

Why is 1 molar aqueous solution more concentrated?

1 molar aqueous solution is more concentrated than 1 molal aqueous solution because 1 molar solution contain 1 mole of solute in 1 litre of the solution which include both solute and solvent. So, the mass of solvent (i.e. water) is less than 1000 gram. … Hence concentration will be more in 1 molar aqueous solution.

What is the mole fraction of solute in 2.5 molar 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.

How do you find the mole fraction of a solute and solvent?

Calculate the mole fraction of the solute by the formula: mole fraction of the solute = moles of the solute / (moles of the solute + moles of the solvent). Calculate the mole fraction of the solvent by the formula: mole fraction of the solvent = moles of the solvent/(moles of the solute + moles of the solvent).

Is the mole fraction of the solute in 2.5 molal aqueous solution?

Answer: 2.5m aqueous solution contains 2.5 moles of solute in 1000g of water.

How do you find the mole fraction of aqueous solution?

How to calculate the mole fraction of a solution? Mole fraction (Xsolute) = moles of solute / (moles of solute + moles of solvent) .

How do you find the mole fraction of a solute?

Calculate the mole fraction of solute by dividing the moles of solute by the total number of moles of substances present in solution.

What is the molarity of a solution containing 200 mg of urea?

Therefore, the molality of solution containing 200 mg of urea (molar mass 60g[mo{l^{ – 1}}]) dissolved in 40 g of water is 0.085 m.
