Question

When aqueous solutions are used for intravenous infusions, it is essential that the molarity of the ions in solution match the molarity of ions in the blood. Blood is approximately 0.31 M, so a solution of sodium chloride for infusion, called saline, must have a concentration of 0.155 M. Calculate the mass of NaCl that solution be used to prepare 5.00 L of a 1.00 M stock solution, and then calculate how many milliliters of the resulting stock solution must be diluted to give 455 mL of 0.155 M solution for infusion.

Answer 1

molarity=moles of solute/L of solution

then M1V1=M2V2
