Solid ammonium chloride, NH4Cl, is formed by the reaction of gaseous ammonia, NH3, and hydrogen chloride, HCl. NH3(g)+HCl(g)⟶NH4Cl(s) A 6.63 g sample of NH3 gas and a 6.63 g sample of HCl gas are mixed in a 1.00 L flask at 25 ∘C. What is the pressure in atmospheres of the gas remaining in the flask? Ignore the volume of solid NH4Cl produced by the reaction.
