36.5% by weight means there are 36.5 g HCl for every 100 g of solution.

36.5 g is 1 mole, while 100 g /1.200 g/ml = 83.33 mL

1 mole / 0.08333 L = 12 M concentrated solution

To make 100 mL of 2 M HCl, use this equation:

McVc = MdVd (c for concentrated, d for dilute)

to figure out how many mL of the concentrated solution you need to dilute to make the solution you want.
