How do you calculate molarity of KCl?
One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5. Add together for the gram-molecular mass of 74.6). If you took 74.6 grams of KCl and diluted this to one liter with water, you would have a 1.00 M KCl solution.

How do you calculate molality?
Molality = nsolute / m solvent = msolute / (W solute * m solvent)
- nsolute is amount of the solute (in moles)
- msolvent is a mass of the solvent (in kg)
- msolute is a mass of the solute (in g)
- W solute is a molar mass of the solute (in g/mol).
