Question

Which conversion factor is needed to solve the following problem?

How many liters of ammonia gas (NH3), can be formed from 54.1 liters of hydrogen gas (H2) at STP?

3H2 + N2 --> 2NH3

Question options:

Molar Volume


Molar Mass of Hydrogen (H2)


Molar Mass of ammonia (NH3)


Avogadro's Number

Answer 1

it is going to be Molar Volume
3H2 + N2 --> 2NH3
54.1L*22.4 L/mol H2 , you can find mol of H2, then mol of NH3, and then L of NH3
