A 780.7 g sample of ammonium carbamate was allowed to decompose at a certain elevated temperature on a 10.0 L sealed container. A 25.0 mL sample of the headspace gas (i.e. the gas above the solid) was removed, and 0.0545 g ammonia could be isolated from that sample. NH4(NH2CO2)(s) = 2NH3(g) + CO2(g). (a) what cncenteration of ammonia, in mol/L was present in the headspace gas? (b) How many moles of ammonium carbamate had evaporated?
