Concept explainers
Interpretation:
The mass of ammonia is to be calculated with given mass of nitric acid.
Concept introduction:
The number of moles is defined as the ratio of mass to the molar mass:
Here,
Molar mass is calculated by adding the masses of each element multiplied by the number of atoms present (given in subscript). Its S.I. unit is
The mass of compound can be calculated as:
Here,
The relationship between pounds and grams can be expressed as
To convert pounds to grams, conversion factor is
