What Molarity of NaCl would give a 300mOsm solution so as to be isotonic to ECF and ICF Set up and solve for X: (cross multiply) 300 mOsm X 2000 mOsmTM Try this on your own, then read on. Show work here: You should have an answer of 0.15 M. If you don't: please ask for help. You need to be able to get that calculation for the next part. Now find the number of grams per liter needed to...
