Question

define the formula unit mass calculate the formula unit mass for Ammonia and Sulphuric acid​

Answer 1

Explanation:

Formula unit mass: The formula unit mass of a substance is the sum of the atomic masses of all atoms in a formula unit of a compound. The term 'formula unit' is used for those substances which are made up of ions.

Ammonia:

Since there are 3 Hydrogen atoms present, the formula mass of H is 1.0 × 3 = 3.0 g/mol. Therefore, by adding them up, the formula mass of ammonia is: [14.0 g/mol + 3.0 g/mol] = 17.0 g/mol.

Sulphuric acid:

The formula for sulfuric acid is H2SO4. The molar mass of sulfuric acid is 98.07848 g mol.
