# What is the mole fraction of solute in an aqueous solution?

Contents

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 solute 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 solute in 30% aq NaOH?

Mole fraction of solute in aqueous solution of 30% NaOH is: A. 0.16.

## How do you find the mole fraction of a solute?

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).

## What is the mole fraction of the solute in a 2m aqueous solution?

of solution= 2m. 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 urea in a 4.45 M aqueous solution?

In an aqueous solution of urea, the mole fraction of urea is 0.2.

## What is the mole fraction of the solute in a 40 by mass?

Explanation: Given one molal aqueous solution. So the mole fraction of solute is the ratio of number of moles of solute divided by the total number of moles present in the solution. =0.018 .

## Is Mole a unit of concentration?

Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.

## What is the mole fraction symbol?

The mole fraction is sometimes denoted by the lowercase Greek letter χ (chi) instead of a Roman x. For mixtures of gases, IUPAC recommends the letter y.

## What is the mole fraction of solute in 10% aqueous caustic soda solution?
