Interpretation: The percent by mass of nitrogen in
Concept Introduction: The percent composition represents the relative amount of the elements in a compound. It is represented as the percent by mass of each element in the compound.
Answer to Problem 35SP
The percent by mass of nitrogen in
Explanation of Solution
The percent by mass of each element in the compound represents the percent composition as:
The percent composition can be determined by the molecular formula of the compound as well as using the relation:
The molar mass of
is determined as:
The moles of N and H are converted to grams of N and H as:
The mass of 1 mol of
Now, determining the percent composition of
Hence, the percent by mass of nitrogen in
