Astudent wants to prepare a 1.0-liter solution of a specific molarity. the student determines that the mass of the solute needs to be 30. grams. what is the proper procedure to follow?
(1) add 30. g of solute to 1.0 l of solvent.
(2) add 30. g of solute to 970. ml of solvent to make 1.0 l of solution.
(3) add 1000. g of solvent to 30. g of solute.
(4) add enough solvent to 30. g of solute to make 1.0 l of solution.
