Asked by Eric

A saline solution is 0.9% NaCl. What masses of NaCl and water would be required to prepare 50. L of this saline solution? Assume that the density of water is 1.000g/mL and that the NaCl does not add to the volume of the solution.
Answered by DrBob222
0.9% NaCl = 0.9 g/100 mL (assume density of 1.00 g/mL and NaCl doesn't add to the volume).
So that would be 0.9 x (50,000 mL/100 mL) = ??

Physiological saline solutions used in intravenous in-
jections have a concentration of 0.90% (mass/volume).
(a) How many grams of are needed to prepare
500.0 mL of this solution?
