The percent by mass of nitrogen for a compound is found to be 46.7%. Which of the following could be this species?
Interpretation Introduction
Interpretation: The formula of the given species is to be stated.
Concept introduction: The number of moles is defined as the ratio of mass with the molecular mass of an element. The mass of an element is the amount of the substance present in an element and the molecular formula of an element defines the total number of atoms present in a molecule.
To determine: The formula of the given species.
Explanation of Solution
Explanation
Given
The percent composition of nitrogen is
The percent composition of compound is
So, the percent composition of oxygen is
The mass of compound is assumed to be
Substitute the values of percent composition of nitrogen and oxygen and total mass of compound in the above formula to calculate their masses.
For nitrogen,
For oxygen,
