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?

You are right. The answer should be E. The answer solution is wrong. 👍
