Question

Ammonia is often produced by reacting nitrogen gas with hydrogen gas.

How many liters of ammonia gas can be formed from 12.9 L of hydrogen gas at 93.0°C and a pressure of 43.5 kPa?

(Assume an excess amount of nitrogen gas.)

I have absolutely no idea how to begin this.

Answer 1

balance the equation:

3H2+N2>>2NH3

so you get 2/3 of the moles of Hydrogen gas..

moles H2=PV/RT

Answer 2

Use PV=nRT. then substitute all the given and you can find the answer.
