Be sure to answer all parts. A 325 mL sample of solution contains 24.3 g of CaCl2.
(a) Calculate the molar concentration of Cl− in this solution. 1.35 M - this one was correct.
(b) How many grams of Cl− are in 0.300 L of this solution? (I got 4.79 g - don't know what i'm doing wrong for this part. Please help!)

Question
A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion. Ag+...
