Given that HCl and NH3 come together to form a solid NH4Cl according to the following reaction: NH3(g) + HCl(g) → NH4Cl(s) If a 2 liter container of HCL and a 5 liter container of NH3 (both at STP) were connected and then allowed to react, what would the final pressure be after the reaction? (Answer should be equal to about 0.4286 atm)
