Question

When a red blood cell is placed in a solution that is more concentrated than the interior of the cell, it can be damaged. Saline solution is intended to be isotonic with animal cells having an approximate concentration of 0.900g sodium chloride per 100 mL of water. To prepare 1.00 liter of saline solution, how many grams of sodium chloride would be needed?

Answer 1

Given that there is a concentration of 0.9 gram of NaCl per 100mL of water.

Therefore for 1000mL ,i.e., 1 litre of water, NaCl requirement is 0.900 × 10 = 9 grams.
