Answer:
2 % of NaCl concentration
The solution is hypertonic to human cells
Explanation:
% Concentration = (g solute / g solution) * 100
Therefore
% Concentration of NaCl = (2 g NaCl/ 100 g solution) * 100
The concentration of the solution equals 2 %
Isotonic solutions for human red cells have a concentration of 0.9 % of NaCl. A concentration of 2 % of NaCl is above 0.9 %, so the solution is hypertonic, since you have more concentration of solute (NaCl) outside the cell, than inside the cell ( inside the side you have only 0.9 % NaCl). So the cell will shrink.
