Respuesta :
The molality of the solvent is 13.8966 m
It would be necessary to know both the solution's density and the
solute's molecular weight.
Explanation:
Molarity = [tex]\frac{mole solute}{L solution}[/tex]
Molality = [tex]\frac{Mole solute }{kg solvent}[/tex]
The solution's density can be used to convert 1 L of the solution's volume into a mass solution. then the substance's molecular weight solute (given or calculated from the formula) can be utilized to change the number of moles mass of the solute in a 1 L solution using grams. The solvent's mass is the difference between the solution's mass and as well as the solute's mass (both of which have been determined). Replace the values and compute using the molality formula.
so the total mass of the solution is 934.4 g,
which leaves 934.4 g − 178.82 g = 755.58 g of
water.
Therefore, the molality is
m = [tex]\frac{10.5 mol NH3}{0.75558 kg solvent}[/tex] = 13.8966 m .
The molality of the nonelectrolyte solid is 13.8966 m.
