molarity of HCl

[RUTH MCMAHON]

In my lab we cannot agree on the molarity of the following solution.
On a bottle of concentrated HCl is the following information,
mw = 36.36
1.19kg = 1L
37%.
There are conflicting views of 
10.15M
11.2M
12.01M.
Could someone please explain the correct way of calculating this. 
Thankyou.

Ruth.
