To create an isotonic solution with 1L of water, approximately 9 grams of NaCl should be added. The discussion clarifies that isotonic solutions are essential for medical applications, such as IV infusions. Participants engage in light banter while confirming the correct amount needed. The calculation is based on molarity, with 1L of water containing about 55.5 moles. Ultimately, 9 grams is established as the necessary quantity for the isotonic solution.

The answer is 9, more or less, the part relating to more vs less and the amount (grams vs kilograms) are left up to you to find out.

I know Borek is going to have a conniption over this :biggrin:

Suppose you were Mark Wahlberg from movie The Shooter, and you needed to figure out how much salt to add to water to infuse into you as an IV solution. How many tea spoons do you think you will need to add to make it an isotonic solution?
