How do you find the mole fraction of 2 molal 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 mole fraction of solute in one molal aqueous solution?

0.018
0.018.

What is a mole fraction of a solute in 2.5 M aqueous solution?

Mole fraction of the solute = 2.52.5+55.56=0.043.

What is the mole fraction of solute in 0.2 molal aqueous solution of urea?

Mole fraction of urea in its aqueous solution is 0.2, them molality of the solution will be. m=0.20.8×100018=25018=13.8 .

What is the mole fraction of the solute in 2.5 M aqueous solution?

0.043
Mole fraction of the solute = 2.52.5+55.56=0.043.

How do you calculate mole fraction?

The mole fraction formula for a solution with containing one or more solutes is: Mole fraction of each solute = Number of moles of that solute divided by the total number of moles of all solutes and the solvent.

What is the formula for calculating mole fraction?

Formula Related to the Mole Fraction Mole fraction of solute = (Moles of Solute) / (Total number of moles of the solutes and the solvent).

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

Solution: 1 molal aqueous solution means 1 mole of solute in 1 kg (or 1000 g) of water. The molecular weight of water is 18 g/mol.

What is the mole fraction of a solute in a solution?

So the mole fraction of a solute in a solvent is given by : number of moles of solute/ (number of moles of solute + number of moles of solvent). 2- molal (m) solution means 2- moles of the SOLUTE is present in 1000- grams of solvent ,here it is water .

What is the solvent of a 2 molal aqueous solution?

Find the mole fraction of solute in its 2 molal aqueous solution. Since it is an aqueous solution, thus the solvent must be water. Was this answer helpful?

How many moles of solute are present in 1000 gram of water?

It is 2.5 m i.e.2.5 molal aqueous solution. That means 2.5 moles of solute are present in 1000 gramof water i.e. 1000/18= 55.5 moles of water are present. Total moles of solute+ solvent= 55.5+2.5= 58. Mole fraction of solute will be (2.5/58)=.0431.

How do you calculate the number of moles of a substance?

The easiest way of calculating the number of moles of any substance is by knowing its mass and, of course, what that substance actually is – i.e its molar mass. So, for example, if 10.0g of sodium chloride are dissolved in water, all you need to know to determine the number of moles of solute is given to you.
