Calculate the volume of ammonia formed by the interaction of 3.5 liters of hydrogen with nitrogen N2 3H2 = 2NH3.

Answer: V (NH3) = 2.46 liters.
Explanation of the solution to the problem: in order to solve this problem, you first need to write down the equation of the chemical reaction: N2 + 3H2 = 2NH3.
Then you need to find the amount of hydrogen substance, for this you need to divide its volume by the molar volume:
n (H2) = V / Vm = 3.5 / 22.4 = 0.16 mol.
Now you need to find the amount of ammonia substance: n (NH3) = 2 * n (H2) / 3, because the reaction shows that hydrogen and ammonia interact in a ratio of 3: 2.
n (NH3) = 2 * 0.16 / 3 = 0.11 mol.
The last step is to find the volume of ammonia, for this we multiply the found amount of the substance by the molar volume:
V (NH3) = n (NH3) * Vm = 0.11 * 22.4 = 2.46 liters.
