Your boss wants you to prepare 200.0 mL, 1.50 osmol/L solution of NaCl.Describe the steps that you would need to take in order to prepare this solutionassuming you only had solid NaCl, water, a balance, and any other laboratorymeasuring devices (such as a graduated cylinder, volumetric flasks, etc). Makesure you perform some calculations before answering this questions so you cantell your boss exactly how much sodium chloride will be required.
