M = moles/L
Answered by Stacy
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???
