FINDING THE FINAL CONCENTRATION WHEN 2 SOLUTIONS ARE MIXED 1. Find the final concentration of the NaCl solution, which is produced by adding 200. mL of 0.500 M NaClto 300. mL of 0.80 M NaCl
2. Find the final concentration of CuSO4 if 750. mLof 0.350 M CuSO4 is combined with 1.15 L of 0.010 M CuSO4.
PREPARING A SOLUTION How would you prepare 500 mL of a 0.20M solution of NaCl?
Dilution Problems 1. If 350 mL of a 2.0 M solution of HCl is diluted to 600 mL by adding water, what is its new concentration?
2. How much water must be added to 800 mLof a 1.5 M NaCl solution to decrease its concentration to 0.40 M?
3. Determine the molar concentration (molarity) of a solution if 15.0 g of NaCl is dissolved in 300 mL of solution.
4. How much water must be added to 250 mL of 0.40 M H2SO4 solution in order to end up with a 0.10 M solution?
