Final answer:
To calculate the amount of sodium chloride in grams contained in a 20 ml nasal spray solution, use the formula: Amount of sodium chloride (g) = Concentration (mol/L) x Volume (L) x Molar mass (g/mol)
Step-by-step explanation:
To calculate the amount of sodium chloride in grams contained in 20 ml nasal spray solution, you need to know the concentration of the sodium chloride in the solution. If you have the concentration in molarity (mol/L), you can use the formula:
Amount of sodium chloride (g) = Concentration (mol/L) x Volume (L) x Molar mass (g/mol)
For example, if the concentration of sodium chloride is 0.1 mol/L and the molar mass of sodium chloride is 58.44 g/mol, the calculation would be:
Amount of sodium chloride (g) = 0.1 mol/L x 0.02 L x 58.44 g/mol = 0.11688 g
