With the equation: N2(g)+3H2(g)->2NH3(g)?

Question

How many L of NH3 gas forms from 20g N2 if the reaction is done at 740 torr and 20C?

Answer 1

First do the stoichiometry. Convert the 20 g of N2 to moles.

Use the molar ratio to calculate moles of NH3.

Now put that into the ideal gas eq. PV=nRT. You already have the pressure and temp. (convert to K). Use 0.082 x 760 for "R" and your answer will be in Liters
