Increasing the temperature of an aqueous solution will cause

Define the following modes of expressing the concentration of a solution: Mass percentage,Molarity,Molality,and Mole fraction. Which of these modes are independent of temperature and why?

The molality of a solution,when $18 \ g$ of glucose is added to $18 \ g$ of $H_2O$,is: (in $m$)

What is the mass of glucose in $500 \ g$ of an aqueous solution of glucose with a molality of $0.5 \ m$?

$30 \ mL$ of $0.5 \ M$ $NaOH$ is diluted to $500 \ mL$ by adding water. What will be the molarity of the diluted solution (in $M$)?

What is mole fraction? Explain in brief.
