Volume of solute / Volume of solution
What does mole fraction represent in a solution?
Ratio of solute moles to total moles in solution
In the context of solutions, what does molarity measure?
Moles of solute per unit volume of solution
How are mass and volume percent related?
They are different ways to express concentration but can be related
Which factor determines the mole fraction value in a given solution?
Both moles of solute and solvent
What happens to the mole fraction if more solute is added to a solution without changing the amount of solvent?
Mole fraction of the solute increases
What is the relationship between mass and mole fractions?
They are different ways to express composition in a solution
In a binary solution, what does a mole fraction value less than 0.5 indicate?
Lower concentration of the component with mole fraction <0.5
