Am I missing info for this Ideal Gas Equation?


Question descriptionSo, this is the balanced equation given

N2 + 3H2 => 2NH3

And we know that N2 is 28.0134g/mol

Given that there are 3L of NH3, how many Liters of N2 are needed?

PV=nRT (equation to be used)

P=1.0526atm

T=291.15K

R=0.08206 Latm/molK

V= 3L of NH3

V=?L of N2

What is ‘n’ and how do I find it? And then how do I find the Volume for the amount of N2 needed to create 3L of NH3?
