Answer:
2.41 g of NaCl is needed
Explanation:
Molarity of solution = (Number of moles of solute)/(Volume of solution in Litre)
Here sodium chloride (NaCl) is solute in saline solution
275 mL = 0.275 L
So, number of moles of NaCl in 275 mL saline solution =
Molar mass of NaCl = 58.44 g/mol
Number of moles = (mass)/(molar mass)
So, mass of 0.04125 moles of NaCl =
So, 2.41 g of NaCl is needed

I believe that what happens here is that when
those cells carrying those intercellular signals do no pass through the
connections, actually the signal is passed through or are transferred to adjacent
cells for signal transmission, hence the answer is:
