above. Keep in mind the definition of molarity.
8. Calculate the final concentration if 2.00 L of
3.00 M NaCl and 4.00 L of 1.50 M NaCl are
mixed. Assume there is no volume contraction
upon mixing.
5. A 0.500 M solution is to be diluted to 500.0
mL of a 0.150 M solution. How many mL of the
0.500 M solution are required?
9. Calculate the final concentration if 2.00 L of
3.00 M NaCl, 4.00 L of 1.50 M NaCl and 4.00 L
of water are mixed. Assume there is no
volume contraction upon mixing.
6. A stock solution of 10.0 M NaOH is
prepared. From this solution, you need to
make 250.0 mL of 0.375 M solution. How
many mL will be required?
