Question

explain ..1) mole fraction 2) molarity 3) molarity​

Answer 1

Mole fraction: It is the ratio of number of moles of one component to the total number of moles present in that solution.

Molality: Molality of any solution is represent the number of moles of solute present in per kg solvent.

Molarity: Molarity of any solution is number of moles of solute per liter of solution.

Explanation:

1)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.2)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.3)Molality is a property of a solution and is defined as the number of moles of solute per kilogram of solvent. The SI unit for molality is mol/kg. A solution with a molality of 3 mol/kg is often described as “3 molal” or “3 m.” However, following the SI system of units, mol/kg or a related SI unit is now preferred
