Question 1 The number of moles of solute dissolved in one liter of solution. Molarity

Question 2 What are 3 ways to speed up a solid solute dissolving in a liquid solvent? stirring crushing increase temperature

Question 3 A solution that contains the maximum amount of solute. saturated solution

Question 4 How do the following speed up dissolving? stirring crushing increasing temperature it disperses/spreads out the solute it increases the surface area it speed up the particles
