Ammonium sulphate is a common chemical used in the production of fertilizer. Ammonium sulphate has high levels of available nitrogen for plants and it is
highly soluble in water. Analysis shows that a water sample has a concentration
of 1.5 mg of ammonium sulphate per 1500 ml of sample.
a) What will be the concentration of ammonium sulphate in this solution in
parts per million?
b) What is the molar concentration of the same compound?

Explanation:

Ammonium sulfate is used most commonly as an artificial fertilizer for alkaline soils. When introduced into damp soil, an ammonium ion is released. This creates a small amount of acid, which lowers the pH balance of the soil. It also contributes nitrogen, which aids in plant growth.

The most common unit of concentration is molarity, which is also the most useful for calculations involving the stoichiometry of reactions in solution. The molarity (M) is defined as the number of moles of solute present in exactly 1 L of solution. It is, equivalently, the number of millimoles of solute present in exactly 1 mL of solution:
