NaCl has a molecular mass of 58 g/mol. Would it go through a 50 molecular weight cut off filter? Why or why not?
Homework Answers
No. One mole of NaCl has 58 grams. We cannot cutoff the molecular weight of NaCl by filter. If we reduce the weight of NaCl, the moles value will decrease but molecular weight will be same. i,e 58.
For example 5.8 grams has 0.1 moles of NaCl. Here weight decreased but not molecular weight.
Moles = weight of NaCl/ molecular weight of NaCl = x/58
X only will change always.
Molecular weight always same for even .01 gram weight of NaCl.

Calculate the percent saline (NaCl) solution that would be isotonic. The molecular weight of NaCl is 58.44 g/mol. Show your calculations. (Hint #1: start with normal cell and plasma osmolality, which is 0.3 Om/kg and convert that to percent saline. Hint #2: NaCl is ionic, so it dissociates in water).
