# How do you find the mole fraction of aqueous solution?

Contents

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.

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

Formula Related to the Mole Fraction

Consider a solution that consists of two substances A and B, then the mole fraction of each substance is: Mole fraction of solute = (Moles of Solute) / (Total number of moles of the solutes and the solvent).

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

The number of moles of the solute A is one mole. Thus, the mole fraction of the solute in a [1.00{text{ }}m] aqueous solution is 0.0177. Hence, the correct answer is option B.

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

Mole fraction of NaOH in an aqueous solution is 0.3.

## What is a mole fraction in chemistry?

The mole fraction, X, of a component in a solution is the ratio of the number of moles of that component to the total number of moles of all components in the solution. To calculate mole fraction, we need to know: The number of moles of each component present in the solution.

## What is the mole fraction of solute in aqueous solution of 30% NaOH?

Mole fraction of solute in aqueous solution of 30% NaOH. Mole fraction of NaOH in an aqueous solution is 0.3.

0.051.

## What is the unit of mole fraction?

Mole fraction is a unit of concentration, defined to be equal to the number of moles of a component divided by the total number of moles of a solution. Because it is a ratio, mole fraction is a unitless expression. The mole fraction of all components of a solution, when added together, will equal 1.

## What is the mole fraction of pure water?

Ans: Mole fraction of water is 0.71 and the mole fraction of ethanol is 0.29.

## What is the moles of water?

One mole of water is 6.022 x 1023 water molecules.

## What is the mole fraction of H2 G )?

XH2 = 0.615
