Questions & Step-by-Step Solutions

In a solution of 1 mol of solute in 9 mol of solvent, what is the mole fraction of the solute?
  • Step 1: Identify the number of moles of solute. In this case, there is 1 mole of solute.
  • Step 2: Identify the number of moles of solvent. In this case, there are 9 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: 1 + 9 = 10 moles.
  • 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 = 1 / 10.
  • Step 6: Simplify the fraction: 1 / 10 = 0.1.
