4.84 grams of NaCl must be combined with water to prepare 510 ml of a 0.95% (m/v) physiological saline solution.
The ratio of the mass of the solute present in a solution to the volume of the solution as a whole is known as the mass/volume percent. The given proportion must be multiplied by 100 because this sort of concentration is expressed as a percentage.
Let number of grams of NaCl combined with water to prepare 510 ml be x grams.
The mass/ volume percent of this solution ⇒ [tex]\frac{x}{510} *100 = 0.95[/tex]
⇒ [tex]x= \frac{0.95}{100} * 510[/tex]
⇒ [tex]x[/tex] = [tex]4.84[/tex]
Therefore, 4.84 grams of NaCl must be combined with water to prepare 510 ml of a 0.95% (m/v) physiological saline solution.
