Concept explainers
Interpretation: The species containing 46.7 % mass percentage of nitrogen needs to be determined from the given options.
Concept Introduction: Mass percentage is the way to calculate the percentage of each element in the given molecular compounds. The mathematical expression of mass percentage can be shown as:
Answer to Problem 9STP
Correct answer: Option (C)
Explanation of Solution
Reason for correct option:
Molar mass of N = 14.00 g/mol
Molar mass of NO = 30.0 g/mol
Calculate the mass percentage of N in each compound:
Thus NO has 46.7% N by mass.
Reasons for incorrect options:
Molar mass of N = 14.00 g/mol
Molar mass of N2O5 = 108 g/mol
Molar mass of NO2 = 46.0 g/mol
Molar mass of N2O = 44.0 g/mol
Calculate the mass percentage of N in each compound:
