Nitrogen and hydrogen gas react to form ammonia gas. At a certain temperature and pressure 1.2 L of N2 reacts with 3.6 L of H2. If all of both gases are consumed what is the final volume of NH3 produced?
The final volume is
Here is the balanced equation
At STP, 1 mole has a volume of 22.4 Liters. To do a dimensional analysis conversion from Liters to moles:
Please observe that Liters and moles vary directly, therefore, we can simply multiply each of the coefficients (that represent moles) by
It does not really matter what number of moles that we have as long as we maintain the
