What are the ways to calculate the molalities of these commercial reagents?
__________________HCl___ __HC2H3O2___NH3 (aq)
Formula weight (amu)____36.465____60.05_______17.03
Density of solution (g/ml)_1.19_______1.05________0.90
Weight %______________37.2______99.8_____28.0
Molarity___________12.1_____17.4____ 14.8

I am confused on how to set up the formulas, especially how many liters there are in the solution.
