What would you need to do to calculate molality of 10g of NaCI in 2Kg of water?
To calculate the molality of a solution, you need to divide the moles of the solute (in this case, NaCl) by the mass of the solvent (water) in kilograms. First, convert the mass of NaCl to moles using its molar mass. Then, calculate the molality by dividing the moles of NaCl by the mass of water in kilograms.
What is the molality of a solution composed of 20.2 g NaCl dissolved in 685 g of water?
The answer is 0,505.
What is is the molality of 3.00 of NaCL and 1.50kg?
m = moles/kg = 3.00/1.50 = 2.00 molal
What would you need to calculate the mole of ten g of NaCl in 2 Kg of water?
You need to know the molar mass of NaCl. Then 10g/molar mass = moles.
The molecular weight of NaCl determined by studing freezing point depression of its 0.5 percent aqueous solution is 30. What the apparent degree of dissociation of NaCl is?
The apparent degree of dissociation of NaCl can be calculated using the formula: i = 1 + (ΔTf)/(Kf * m), where i is the van't Hoff factor, ΔTf is the freezing point depression, Kf is the cryoscopic constant, and m is the molality of the solution. Given the information, assuming Kf for water is 1.86 °C kg/mol and the molality is 0.5 mol/kg, you can calculate the van't Hoff factor to determine the apparent degree of dissociation.

What would you need to calculate the molality of 10 g of NaCI in 2 kg of water?
To calculate the molality of 10 g of NaCl in 2 kg of water, you need to determine the number of moles of NaCl and the mass of the solvent (water) in kilograms. First, calculate the molar mass of NaCl, which is approximately 58.44 g/mol. Then, divide the mass of NaCl (10 g) by its molar mass to find the number of moles, and finally, use the formula for molality: molality = moles of solute / mass of solvent (in kg). In this case, the calculation would be molality = (10 g / 58.44 g/mol) / 2 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 you need to do to calculate the molality of 0.2 kg of NaCl on 3 Kg of water?
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.
