Q: What is the mole fraction of solute in a solution containing 2 moles of solute and 8 moles of solvent?
Solution: Mole fraction of solute = moles of solute / (moles of solute + moles of solvent) = 2 / (2 + 8) = 2 / 10 = 0.2.
Steps: 6
Step 1: Identify the number of moles of solute. In this case, there are 2 moles of solute.
Step 2: Identify the number of moles of solvent. In this case, there are 8 moles of solvent.
Step 3: Calculate the total number of moles in the solution by adding the moles of solute and moles of solvent together: 2 moles (solute) + 8 moles (solvent) = 10 moles (total).
Step 4: Calculate the mole fraction of the solute using the formula: mole fraction of solute = moles of solute / total moles.
Step 5: Substitute the values into the formula: mole fraction of solute = 2 moles / 10 moles.
