What is the mole fraction of solute in a solution containing 3 moles of solute and 7 moles of solvent?
Correct Answer: 0.3
Step 1: Identify the number of moles of solute. In this case, there are 3 moles of solute.
Step 2: Identify the number of moles of solvent. In this case, there are 7 moles of solvent.
Step 3: Calculate the total number of moles in the solution by adding the moles of solute and solvent together: 3 moles (solute) + 7 moles (solvent) = 10 moles (total).
Step 4: Calculate the mole fraction of the solute by dividing the moles of solute by the total moles: 3 moles (solute) / 10 moles (total) = 0.3.
Step 5: The mole fraction of the solute is 0.3.
