Answer :
The mass of sodium chloride that is present in a liter of solution that has 4.50 x 10⁻⁶ kg of sodium per liter is 45 mg.
What is the mass of sodium chloride in milligrams that is present in a liter of solution that has 4.50 x 10⁻⁶ kg of sodium per liter?
The mass of sodium chloride in milligrams that is presents in a liter of solution that has 4.50 x 10⁻⁶ kg of sodium per liter is calculated as follows:
- mass = mass concentration * volume in liters
Mass concentration of sodium chloride solution = 4.50 x 10⁻⁶ kg of sodium chloride per liter.
Volume of solution = 1 liter
Mass of sodium chloride = 4.50 x 10⁻⁶ kg/L * 1 L
mass of sodium chloride = 4.50 x 10⁻⁶ kg
mass of sodium chloride = 4.50 x 10⁻⁶ kg * 1000000 mg/kg
mass of sodium chloride = 45 mg
