A 10.0 mL sample of NaCl solution is poured into an evaporating dish with a mass of 24.10g in a lab experiment. The combined mass of the dish and solution is having 36.15g. The solution is evaporated. After this process, the dish and the dry NaCl have a combined mass of 25.50g.
1. Determine the % (w/v) of the NaCl solution?
2. Determine the molarity (M) of the solution?
What is the M of the diluted solution if water is added to 10.0ml of the initial NaCl solution to give a final volume of 60.0 mL.
