A very dilute solution is prepared by dissolving 'x₁' mole of solute in 'x₂' mole of a solvent. The mole fraction of solute is approximately equal to

ANS:A - x₁/x₂

To find the mole fraction of the solute (𝑋1X1​), we use the formula: 𝑋1=moles of solutetotal moles in solutionX1​=total moles in solutionmoles of solute​ In this case, the total moles in the solution is the sum of the moles of solute (𝑥1x1​) and the moles of solvent (𝑥2x2​). So, the mole fraction of the solute (𝑋1X1​) is: 𝑋1=𝑥1𝑥1+𝑥2X1​=x1​+x2​x1​​ Thus, the mole fraction of the solute is approximately equal to 𝑥1𝑥1+𝑥2x1​+x2​x1​​. Therefore, the correct option is 𝑥1𝑥1+𝑥2x1​+x2​x1​​.
