Question
The percentage of nitrogen in ammonia is given by the expression
Select an answer
A 14 × 10017
B 317 × 100
C 14 × 10034
D 334 × 100
Solution
The percentage of nitrogen in ammonia can be calculated using the formula:
% of Nitrogen = (Mass of Nitrogen / Molar mass of Ammonia) * 100
The molar mass of Nitrogen (N) is approximately 14 g/mol, and the molar mass of Ammonia (NH3) is approximately 17 g/mol (14 g/mol for the Nitrogen atom and 1 g/mol for each of the three Hydrogen atoms).
So, the percentage of Nitrogen in Ammonia is:
% of Nitrogen = (14 / 17) * 100
Therefore, the correct answer is A : 14 × 100/17.
