If 200ml of a 4M solution of NaOH and 300ml of a 6M solution of NaOH are mixed what will the molarity of the resulting solution be?
1 Answer
The molarity of the
Explanation:
To determine the molarity of the mixture of the two solutions, you need to convert the volume of each solution from mL to L. Then you need to determine the mol NaOH in each solution by multiplying the molarity of each solution by its volume in L.
Then you determine the total moles and total volume. Determine the molarity of the mixture by using the molarity formula, with the total moles and total volume.

Molarity of the mixture of the two solutions
Add the moles of the two solutions.
Add the volumes of the two solutions.
The molarity of the mixture is the total moles divided by the total volume.
