What information is needed to determine a molecular formula?

To determine a molecular formula, you must know the gram formula mass of the compound as well as the empirical formula (or enough information to calculate it yourself from the percent composition).

How do you determine molecular mass?

Molecular Mass Problem Find the atomic mass for each element by using the mass given in the Periodic Table. Multiply the subscript (number of atoms) times the atomic mass of that element and add the masses of all of the elements in the molecule to get the molecular mass.

What is the formula for ammonium oxide?

Chemical formula of ammonium oxide is (NH4)2O.

What is the formula for ammonium sulfate?

(NH₄)₂SO₄Ammonium sulfate / Formula
Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH4)2SO4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21\% nitrogen and 24\% sulfur.

How do you identify ammonium sulfate?

Ammonium ions can be identified in a solution by adding dilute sodium hydroxide solution and gently heating. If ammonium ions are present, they will be converted to ammonia gas. Ammonia has a characteristic choking smell. It also turns damp red litmus paper or damp universal indicator paper blue.

How do you calculate ammonium sulfate?

Multiply the initial sample volume (100 ml) by the multiplication factor (0.538) to calculate the volume of the saturated ammonium sulfate solution required (53.8 ml). 3. Slowly add the calculated volume (53.8 ml) of the saturated ammonium sulfate solution to 100 ml of the protein sample with gentle stirring.
