Q: If the mole fraction of a solvent in a solution is 0.8, what is the mole fraction of the solute?
Solution: The mole fraction of the solute is 1 - X_solvent = 1 - 0.8 = 0.2.
Steps: 7
Step 1: Understand that the mole fraction of a solution is the ratio of the number of moles of a component to the total number of moles in the solution.
Step 2: Recognize that the mole fraction of the solvent is given as 0.8.
Step 3: Remember that the sum of the mole fractions of all components in a solution equals 1.
Step 4: Use the formula: Mole fraction of solute = 1 - Mole fraction of solvent.
Step 5: Substitute the value of the mole fraction of the solvent into the formula: Mole fraction of solute = 1 - 0.8.
Step 6: Calculate the result: 1 - 0.8 = 0.2.
Step 7: Conclude that the mole fraction of the solute is 0.2.
