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

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
