We’re being asked to calculate the molarity (M) of a solution of LiF.
Recall that molarity is the ratio of the moles of solute and the volume of solution (in liters). In other words:
We’re given the molality of the solution, 0.0433 m LiF.
Recall that the molality (m) is the ratio of the moles of solute and the mass of solvent (in kg):
This means the solution of LiF is:
The steps we need to do for this solution are:
Step 1: Calculate the mass of LiF
Step 2: Calculate the mass of the solution.
Step 3: Convert the mass of the solution to volume (in L).
Step 4: Calculate the molarity of the solution.
What is the molarity of the solution 0.0433 m LiF, if the density is 1.10g/mL?
