Solid ammonium chloride, NH4Cl, is formed by the reaction of
gaseous ammonia, NH3, and hydrogen chloride,
HCl.NH3(g)+HCl(g)⟶NH4Cl(s)
A 6.37 g sample of NH3 gas and a 6.37 g sample of HCl gas are
mixed in a 1.00 L flask at 25 ∘C.
How many grams of NH4Cl will be formed by this reaction?
What is the pressure in atmospheres of the gas remaining in the
flask? Ignore the volume of solid NH4Cl produced by the
reaction.
