Describe how to prepare 250mls of a 0.35M NaCl solution:
1. Assume you are starting with a 2M NaCl solution
2. Record how much 2M NaCl and water you will use to do
this
Assume you have a solution (Solution A) :
1. Summarize how you would make 250mls of a 1:5 dilution
Describe how to prepare 500mls of a 0.20M CaCl2 solution:
1. Assume you are starting with a 3M CaCl2 solution
2. Record how much 3M CaCl2 and water you will use to do
this
Assume you have a solution (Solution A) :
1. Summarize how you would make 750mls of a 1:4 dilution
2. Assuming Solution A (above) was 0.65M, what would the
final concentration be for the 1:4 dilution?
