A reaction requires 15.0 g of ammonium chloride. The percent by mass of ammonium chloride in the solution is 14%. The mass of the solution required is:
15.0 g ammonium chloride × (100 g solution/ 14 g ammonium chloride) = 107 g solution
The density of the solution is 1.04 g/cm³. The volume of solution corresponding to 107 g is:
107 g × (1 cm³/ 1.04 g) = 103 cm³
In 103 cm³ of a 14% solution, there will be 15.0 g of ammonium chloride.
