Question

1) If I add 10 grams of salt into 0.1 L of water, what is the molarity of the solution?

2) Serial dilution is a common technique to make low concentration solutions. Each Serial Dilution involves taking half the solution and mixing it with a solvent, to halve the concentration. If the solution from problem 1 undergoes 5 serial dilutions, what will the molarity of the final solution be?
