What would you need to do to calculate the molality of 10g of nacl in 2g of water?
To calculate the molality of a solution, you need to know the moles of solute (in this case, NaCl) and the mass of the solvent (water). First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality using the formula molality = moles of solute / mass of solvent in kg.
What would you need to do to calculate the molality of 0.2kg of nacl in 3kg of water?
To calculate the molality of a solution, you need to know the moles of solute and the mass of the solvent in kilograms. First, calculate the moles of NaCl in 0.2 kg: moles = mass (g) / molar mass. Then, calculate the molality by dividing the moles of solute by the mass of solvent in kg: molality = moles of solute / mass of solvent in 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.
The density of 3 M solution of NaCl is 1.25 g mL-1 Calculate the molality of the solution?
To calculate the molality of the solution, you first need to find the molar mass of NaCl, which is 58.44 g/mol. Next, calculate the mass of NaCl in 1 L of the solution by multiplying the density (1.25 g/mL) by 1000 mL. Then divide the mass of NaCl by the molar mass to find the number of moles. Finally, divide the moles by the mass of the solvent (in kg) to get the molality. In this case, the molality is approximately 1.30 mol/kg.
What mass of nacl would have to be dissolved in 1.000kg of water to raise the boiling point by 2.00c?
To calculate the mass of NaCl needed to raise the boiling point of water by 2.00°C, you can use the formula ∆Tb = iKbm, where ∆Tb is the boiling point elevation, i is the van't Hoff factor (2 for NaCl), Kb is the ebullioscopic constant for water, and m is the molality of the solution. You first calculate the molality using the given data and then find the amount of NaCl needed.

What would you need to do to calculate the molality of 10 mol of NACI in 200 mol water?
To calculate the molality of NaCl in a solution, you would need to divide the number of moles of solute (NaCl) by the mass of the solvent (water) in kilograms. Since you have 10 mol of NaCl and 200 mol of water, you first need to convert the moles of water to kilograms. Given that the molar mass of water is approximately 18 g/mol, 200 mol of water corresponds to 3600 g, or 3.6 kg. Finally, calculate the molality using the formula: molality (m) = moles of solute / kilograms of solvent, resulting in 10 mol / 3.6 kg.
