Molality is expressed as moles solute/kg solvent. Moles of solute = 2. Kg solvent = 6.Molality = 2 moles/6 kg = 0.33 molal
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kilograms. In this case, with 2 moles of NaOH dissolved in 10 kg of water, the molality would be 0.2 mol/kg.
Molality =moles of solute/kilograms of solvent Moles of solute =2
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kg. First, calculate the moles of ethanol using its molar mass and mass given, then convert the mass of water to kg. Finally, use the formula molality = moles of solute / kg of solvent to find the molality.

Finally, use the formula molality = moles of solute / kg of solvent to find the molality.
Molality is defined as moles of solute per kg of solvent. Thus, 3 moles/6 kg = 0.5 moles/kg = 0.5 m
10kg of water contains 10l of water. So morality is 0.2mildm-3.

The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kg. In this case, there are 2 moles of NaOH dissolved in 6 kg of water. Therefore, the molality would be 2 mol / 6 kg = 0.33 mol/kg.
Molality is moles solute per kilograms of solvent, so 2/10=0.2m.
The molality of a solution is calculated by dividing the moles of solute by the mass of the solvent in kg. In this case, the moles of NaCl is 3.0 and the mass of water is 1.5 kg. Therefore, the molality of the solution is 2.0 mol/kg.
