To calculate the molality of NaCl in water, first, determine the number of moles of NaCl by dividing the mass of NaCl (0.2 kg or 200 g) by its molar mass (approximately 58.44 g/mol). Then, divide the number of moles of NaCl by the mass of the solvent (water) in kilograms (3 kg). The formula for molality (m) is m = moles of solute / mass of solvent in kg.

What is the molality of .630g of NaCl dissolved in 525g of water?

To find molality, first convert grams of NaCl to moles: 0.630g NaCl / 58.44 g/mol NaCl = 0.0108 mol NaCl. Next, calculate molality using moles of solute and mass of solvent: molality = moles of solute / kg of solvent = 0.0108 mol NaCl / 0.525 kg water = 0.0206 mol/kg.

What would the final freezing point of water be if 3mol of NaCl were added to 1kg of water?

The freezing point depression constant for water is 1.86°C kg/mol. First, calculate the molality of the solution: 3 mol NaCl / 1 kg H2O = 3 mol/kg. Next, calculate the freezing point depression: ΔTf = iKfm where i is the van't Hoff factor (2 for NaCl), Kf is the freezing point depression constant, and m is the molality. Plugging in the values, the final freezing point would be -11.16°C.
