What is the ratio by mass of nitrogen and hydrogen in ammonia?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 14 : 3.
The ratio by mass of nitrogen to hydrogen in ammonia (NH3) is 14:3.
This indicates that in every 14 grams of nitrogen, there are 3 grams of hydrogen in the ammonia molecule.
This ratio represents the chemical composition of ammonia, where one nitrogen atom combines with three hydrogen atoms to create the ammonia molecule.
