• In the food industry, we generally add 1 mL of a substance to 99mL of water to obtain a 1:100 dilutiọn
  In the hospital clinic, we generally add 0.1mL of urine to 9.9mL of water to obtain a 1:100 dilutiọn
  
  Why do we use two different amounts to obtain the same dilution?

  it has to do with how much substance you have available and the amount of solution you need. if you need only 10 ml of some solution, making a 100 ml solution would be wasteful.
