What is the molality of a solution of 75.2 g AgClO4 dissolved in 885 g C6H6?
To calculate molality, we first need to find the moles of AgClO4 and the moles of solvent, C6H6. Calculate moles of AgClO4: 75.2 g / molar mass of AgClO4 Calculate moles of C6H6: 885 g / molar mass of C6H6 Then, molality (m) = moles of solute / kg of solvent. Divide the moles of AgClO4 by the kg of C6H6 to find the molality of the solution.
How can one determine the molar mass from molality?
To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.

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.
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 is the molality of a solution containing 10.0g of Na2SO4 dissolved in 1000.0g of water?
To find the molality, we first calculate the moles of Na2SO4: 10.0g Na2SO4 * (1 mol Na2SO4 / 142.04g Na2SO4) = 0.0705 moles Na2SO4. Then, molality is calculated as moles of solute (Na2SO4) / kilograms of solvent (water): 0.0705 mol / 1.000 kg = 0.0705 mol/kg, which is the molality of the solution.
How can one determine the molality of a solution using the freezing point depression method?
To determine the molality of a solution using the freezing point depression method, you need to measure the freezing point of the pure solvent and the freezing point of the solution. By comparing the two freezing points, you can calculate the change in temperature. Using the formula T Kf m, where T is the change in temperature, Kf is the cryoscopic constant of the solvent, and m is the molality of the solution, you can solve for the molality of the solution.
