Fluid therapy is a critical component in the clinical management of many medical patients. Theconcentration of saline solution (NaCl) recommended for this therapy depends on the medicalneeds of the patient. To maintain electrolyte balance, the doctor prescribes a dosage of no morethan 0.0077 moles of NaCl in 100 mL of the saline fluid. The available saline solution is 0.154M, packaged in 1-liter quantities. How many mL of this concentrated solution do you need toprepare 100 mL of the desired dosage?
