Problem

How many moles of KF are contained in 244 mL of 0.135 m KF solution?  The density of the solution is 1.22 g/mL

Solution

We’re being asked to determine the moles of KF in 244 mL of 0.135 m KF solution.


Recall that molality is the ratio of the moles of solute and the mass of solvent (in kilograms)


In other words:


Molality (m)=moles solutekg solvent
