Describe how you would prepare each of the following aqueous solutions, starting with solid KBr: (a) 0.75

Question:

Describe how you would prepare each of the following aqueous solutions, starting with solid KBr:
(a) 0.75 L of 1.5 × 10-2 M KBr,
(b) 125 g of 0.180 m KBr,
(c) 1.85 L of a solution that is by mass (the density of the solution is 1.10g/mL),
(d) A 0.150 M solution of KBr that contains just enough KBr to precipitate 16.0 g of AgBr from a solution containing 0.480 mol of AgNO3?
