## 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 .

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.
