The formula mass of any compound is described in units of amu.

Explanation:

Molecular formula is the actual number of atoms of each element in the compound.

The mass of one molecule of the compound is known as formula mass. Thus, the unit of formula mass is amu.

For example, sodium chloride has a molecular formula of NaCl. The formula mass of NaCl is 58.44 amu.

Thus, the formula mass of any compound is described in units of amu.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
