    I think this question is wrong but just want to make sure that i am not doing it wrong or anything!

    If enough H2o is added to a 11grams of CaCl2 to make 100mL of solution, what is the molarity?
    A. 9M
    B. 10M
    C. 11M
    D. 12M
    E. NONE OF THE ABOVE

    *the correct answer is B, but when I did it, I got E. Here is how I did it:
    11g of Cacl2/110(g/mole) = .1 mole of CaCl2
    Then, M = mole/L, so .1/.1L of sol'n = 1M

    Am i doing it wrong?
