Question

What is the Molar mass of Ammonia $N{H}_3$ ?

Answer 1

Hint: The molar mass is the mass of a given element or compound (g) divided by the quantity of substance (mol). The molar mass of a compound is often calculated by adding the quality atomic masses (in g/mol) of the constituent atoms.

Complete answer:
Ammonia formula also mentioned as nitrogen trihydride formula or azane formula is one among the foremost popular formulas in chemistry. Ammonia is essentially a colourless inorganic or alkaline gas having a definite pungent odour. The compound ammonia is further a crucial source of nitrogen for several applications in chemical and industrial processes.
Ammonia formula is given as NH3. The formula springs from the chemical structure of ammonia where: The ammonia molecule exhibits a trigonal pyramidal shape with nitrogen attached to the three hydrogen atoms. The nitrogen atom, on the opposite hand, features a lone electron pair.
To estimate the molar mass of any compound, we've to include the molar masses of each atom of the given compound. Ammonia comprises 1 nitrogen atom and three hydrogen atoms. therefore the molar mass of ammonia is:
N: 14.0067 g/mol.
H: 1.00794 g/mol.
The molar mass of ammonia will thus be 14.0067 g/mol +3× 1.00794 g/mol =17.03052 g/mol
Hence, Molar mass of ammonia is 17.03052 g/mol.

Note :
The characteristic molar mass of a component is just the mass in g/mol. However, molar mass also can be calculated by multiplying the mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the mass of the constituent atoms.
