Volumes?? (1 Viewer)

[Premus]

When 1.5L of HCl gas and 1.8L of NH3 gas are mixed, a white solid of NH4Cl is formed. calculate the mass of NH4Cl formed if the gas volumes were measured at 25 degrees and 101.3 kPa.

i get an answer of 3.28 g

Thanks!

HCl + NH3 --> NH4Cl
v/mv = m/mm
m = (v x mm)/mv
m = (1.5 x 53.492)/ 24.47
m = 3.279g
