Question

How would you find the number of grams of NH3 that is produced from 35 L of N2 at 200 atm pressure and a temperature of 450 degrees C?

Answer 1

3H2 + N2 <--> NH3 If 35 L of N2 then 70L of NH3 PV = nRT so n = PV/RT

200 x 70 / 8.314 x 723

Answer 2

That get's n = number of mols at the conditions listed, then mols = grams/molar mass and solve for grams.
