calculate the molarity of each of the following solutions. Help!!

(a) 0.36 mol of LiNO3 L of solution

(b) 70.7 g C2H6O in 2.25 L of solution

(c) 11.56 mg KI in 114.2 mL of solution

  2. the first one (a) I was suppose to write 6.36L of LiNO3 soooooo but ur M=moles/L
    I take 0.36/6.36L and get 0.0566 and i'm suppose to give the answer in 2 significant figures which I think is 0.05 but it I got it wrong.......the anwser is

    M= 5.5x10-2 M

    what did i do wrong???
