What is the mole fraction of acetic acid in this solution?
The mole fraction of acetic acid (CH_3COOH) in an aqueous solution is 0.675.
How do you find the mole fraction of an acid?
Calculate the mole fraction of solute by dividing the moles of solute by the total number of moles of substances present in solution. Calculate the molarity of the solution: moles of solute per liter of solution.

What will be the molarity of a solution, which contains 5.85 g of NaCl(s) per 500 mL? Molarity=Moles of the soluteVolume of solution in L=5.85/58.50.500L=0.2 mol L-1.
How do you find the mole fraction of a solute and solvent?
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 acetone?
Calculate the mole fraction of acetone in the solution containing 1 mole of benzene, 2 moles carbon tetrachloride and 7 moles acetone. Answer: Mole fraction of acetone is 0.7. Solution: Number of moles of acetone = 7 moles. Total number of moles in the solution = Number of moles of benzene + number of moles of.
How do you find the mole percentage of a mixture?
1. In the given mixture, sum of all the mole fractions is equal to one. 2. The multiplication of the mole fraction by 100 gives the mole percentage. 3. Mole fraction is a unitless and dimensionless expression. Mole fraction is not dependent on the temperature.
What is a mole fraction in chemistry?
Mole fraction refers to a unit of concentration. It is a formula in the field of physics that is unitless expression. Mole fraction is equal to the number of a component’s moles divided by the total number of a solution’s moles. Also, when analyzing the solutions chemist use mole formula to measure the concentration of components.
How do you find the molar fraction of a solution?
Mole Fraction formula. The molar fraction can be represented by X. If the solution consists of components A and B, then the mole fraction is, =. Therefore, the sum of mole fraction of all the components is always equal to one.
