If a solution is made by mixing 50.0 moles of KOH to 3.4 kilograms of water, what is the solutions molality?
To find the molality of a solution, we need to know the moles of solute (KOH) and the mass of the solvent (water) in kilograms.
First, let's convert the mass of water from grams to kilograms:
3.4 kilograms of water = 3400 grams of water
Next, we calculate the molality using the formula:
Molality (m) = moles of solute / mass of solvent (in kg)
Given that we have 50.0 moles of KOH and 3400 grams of water:
Molality (m) = 50.0 moles / 3.4 kg
= 14.71 mol/kg
Therefore, the molality of the solution is 14.71 mol/kg.
