Change all to mole, so we can compare
MW of NH3 = 17 g/mol
MW of CO2 = 44 g/mol
Mw of H2O = 18 g/mol
mol of NH3 = mass / MW = 50/17 = 2.94
mol of CO2 = mass / MW = 80/44 = 1.82
mo of H2O = 2
make sure the balance is correct:
it is, (count of C,H,N,O are correct)
so
1:1:1 ratio is correct
1.82 mol of CO2 will limit
therefore
only 1.82 mol of NH4HCO3 can be produced
mass = mol*MW = 1.82*79.056 = 143.88192 g of NH4HCO3 can be produced

Carbon dioxide dissolves in water to form carbonic acid, which is primarily dissolved CO_2. Dissolved CO_2 satisfies the equilibrium equation CO_2(g) CO_2(aq) K=0.032 M atm^-1 The acid dissociation constants listed in most standard reference texts for carbonic acid actually apply to dissolved CO_2. For a CO_2 partial pressure of 7.1x10^-4 atm in the atmosphere, what is the pH of water in equilibrium with the atmosphere?
