Question

1) Calculate the percent composition of each element in ammonia (NH).

Answer 1

`\% N=82.2\% \\\\\% H=17.8\%`

Step-by-step explanation:

Hello there!

In this case, since ammonia is NH₃, we can see nitrogen weights 14.01 g/mol and hydrogen 3.03 g/mol as there is one only nitrogen atom and three hydrogen atoms; thus, the total mass is 17.04 g/mol. In such a way, the percent composition of each element turns out to be:

`\% N=(14.01)/(17.04)*100\%=82.2\% \\\\\% H=(3.03)/(17.04)*100\%=17.8\%`

Best regards!
