Answer to: Calculate the molality of 6.00 M H_2SO_4 solution. The density of the solution is 1.34 g/mL. By signing up, you'll get thousands of...
Aside from the molarity, we can also express the amount in moles of solute present by using molality. We use the molality to express the concentration of solution when studying colligative properties. The molarity is a temperature dependent concentration unit while the molality is a non...
Molality can be defines as the moles of the solute per kilograms of the solvent. The molality of a solution is generally reported in units mol/kg. The molality of a solution can be calculated using the following equation: ΔTf=Kf×m ...
